Any flash guns with FP mode off camera?

One of the things I have been doing with off camera flash (FL50's) is that I have been using Aputure transmitter and receivers and actually using my Sekonic L358 light meter.  Although not true FP mode as I am in manual mode I set the Sekonic to flash.  I trigger the strobe and I get an ambient reading plus turning the dial to at least 30% flash.

I can light the subject but you do not notice the  flash except for the catch lights in the eyes. The images look natural. If you increase the percentage (either turning the dial and resetting the fstop and shutter) the ambient will darken.  I have had this light meter for a few years used it for ambient or setting up 3 FL50's for portraits.  I have been exercising on a stationary bike and catching up on my podcasts and I caught a Brady podcast.
