Taking a picture

Hi all. Just a quick question.
When taking still shots on my smart controller, is there any way other than pressing the white shutter icon on the screen? Is there anyway to use the dji main focus/shutter button on the controller. It would be far easier.
Use litchi mission hub everyday for waypoints and its great.
Love it.

It’s my first post on here so sorry if I’ve put it in the wrong place.
