Mars II Play Once Option

Hi - apologies if this has been asked before but when using the Mars II projector it always starts playing next video file unless I put it on loop. There doesn’t seem to be any option to play once and then stop. The reason being I’m giving presentations and using multiple files and don’t want it to repeat or skip to next. Only option I have is to ensure I press stop / return to menu right at end or add in ‘filler’ videos in between. Would love to have option to play once and then it simply returns to menu. Thanks
