For DJ's attention.  I understand this feature works for a limited number of cameras.  I am using the RS3 Pro.  The feature supposedly works with the Nikon Z6ii, however I am using the very similar Nikon Z7ii.  On the Z7ii, that feature activates the camera's "playback" button - not useful at all!  Any hope of a firmware update to properly map the RS3 Pro M buttorn to the Z7ii "Fn1" button instead?  Since the Fn1 button can be programmed for subject tracking (auto-focus), this would be extremely useful.
