Panasonic face detect AF: multiple people, face turning away

I find that face detect autofocus works very well on my G85, as it did on my previous GH4, E-M5, and GX1. However, there are two situations where it doesn't work so well:

1. If there are multiple people, there's no way to select which face to focus on.

2. If the face turns away, there's no guarantee on what you'll get next. It might be a different face (see above), or the body.

Do newer Panasonic cameras provide solutions for these situations? For example, the G9 manual says:

To specify the person or eye to be brought into focus, align an AF area with the desired person or eye. You can do so easily by touching a person indicated with an AF area.
I'm not sure what "align an AF area" means, because I didn't think there were AF areas in face detect. I'd rather not use the touch screen, since that doesn't work well for me when using the EVF. (My nose presses the screen.)

My old Olympus E-M5 had the nice behavior where you could specify a focus point to fall back on if face detect failed. That provided a work around for the second situation but not the first. With Panasonic cameras I've used, if you select a focus point--which requires a button or touch screen press--that disables face detect. I find the Panasonic way simpler to understand, but the Olympus a little bit better in practice--and still not ideal.

I know certain other, ahem, tony manufacturers solve this differently, but I don't want to get into a system debate. I'll say that the need for true continuous face AF doesn't really matter for me. I'm talking about relatively static subjects here, and a relatively slow FPS.

I think that at Photokina 2018, Panasonic demonstrated that this is not a problem with the newest models (see the DFD depth chart videos).

I believe if the camera detects more than one face, it marks them with boxes (areas), that can be selected by tapping the screen. Personally, I almost never use face detection AF.

Is it an option for you to flip the screen to the left and keep it there? This way, your nose does not touch it, and it is easy to rotate it up and down.

When I close the screen, it is always facing the camera body. When the screen is visible (facing my body, pun intended), it is always flipped to the left side. This works perfectly for me. Using screen closed but facing me would cause all kinds of problems, such as nose activating AF and unnecessary rotational process when I want to make use it as an articulating screen (almost always).

I know that for some people, for some reason, the kind of operation I suggested is out of the question. In my opinion, it is absolutely the best way to use articulating screens.
 
At least part of this will hopefully be addressed with a future firmware update. The new S1 and S1R when multiple people/faces are detected you can click the joystick to switch the focus from one to the other and it will cycle through them.
 
That would be lovely. But it also needs to lock on to that face, i.e., prefer it over others once selected.
 
I believe there is a way to lock it on, its been a while since I had one in my hands though so cannot confirm off the top of my head

wish the G9 had this. Never use touch screen with stills as accidental touching it moves focal point unexpectedly.
 
Yeah I am REALLY hoping it comes in firmware - seems like it would be a fairly simple thing to implement
