Allow mapping missions without automatic photo capture

I’d love an opportunity to “turn-off” automatic photo capture during a mapping mission. We are developing a workflow to routinely fly over parking lots at night to monitor for suspicious/criminal activity. A mapping flight is great because it follows the same grid-like pattern at a pre-determined altitude every time. This allows us to focus most of our attention to the live IR camera feed on our drone (M3T). But we don’t need the drone to take photos during these flights. Why can’t there be an on/off option in the advanced settings where we can turn the automatic photo capture to “off”? (I don’t want to pull the SD card as a workaround, because I’d still like the option to manually take photos if I see something suspicious.)
