M2 shutter count wrong

hi Julia,
When I fly only with HSA to M2, it seems to work. BUT I still would like to have a feedback for my fc because I do not see if the camera is taking photos. Is there a way to connect a cable from M2 to FC as a feedback for shutter? It’s very annoying not to get feedback. I just flew 2.5 hrs just to see that the SD card got full during flight. With feedback to FC, I would have seen it.
