4 channel audio: Stereo analog + digital multi-shoe interface?

Hi, my A7iv says it supports 4 channel audio, but is very vague about what that means.

I'm thinking about buying the Sony ECM-B1M, which is a hotshoe mic that records digitally to the camera without needing a 3.5mm cable,

so my question is, if that's connected digitally, would that mean I could ALSO connect an analogue mic through the 3.5mm input?

That way I could have the Sony ECM-B1M record a shotgun mono channel, as well as having my Rode Stereo VideoMic recording a stereo audio, and then in post decide which one I want to use.

I can't find any information if that's possible, and since it's a very expensive microphone I don't feel like "buying just to find out", does anyone know?

Gotcha, so basically it's impossible if you do gimbal shooting. That's unfortunate.

Not totally, hot shoe extension, but it is a ton of added complexity

Have you considered an inexpensive external audio recorder? That wouldn't have to be on the gimbal, and it's pretty easy to sync up the tracks in post.

Yeah the mic I have attached to my gimbal now is the Zoom H1n, except I have it plugged into the camera's analogue mic input instead of using it as a recorder. I've never understood people who says its easy to sync in post, as I find it to be anything but. It must be dependent on style of shooting, I like being able to just go around and take short clips of little things for example when I'm walking the dog, it would be a huge organization nightmare to sync everything in post, especially if it's only years later when I decide to turn some clips into a published video.

Oh I see, I had no idea such a solution existed, as well as being provided with the Sony XLR-K3M. Well, I suppose the Sony XLR-K3M is a bit too bulky anyway, even if just attached to the handle of the gimbal rather than the camera.
