Custom button videos

idk how feasible it is wirh the apps storage system, but would be cool to either be able to upload mutiple videos to one custom button/trigger……. or to be able to be able to link buttons together to trigger at the same time, or to have one button end by triggering another……. the main use case for this is to have a different video display on each screen ( for the Olympics i wanted a button that chants USA and I wanted a U on my left monitor, An S on my middle and A on my right) or another use case I like to set up pre game or intermission hype videos trigger by buttons but they only play 1 min at a time so if i could set up 2 buttons each with there own video and when button A videos done then it will trigger button B
