Something like plugin~ / plugout~ but for VIDEO???

Hi, greetings to all!

Somebody knows if there is something like plugin~ / plugout~ but for video? ("VIDEO from Live - VIDEO to Live")

I would like to add multiple max video devices on a track, and that each one send the video processing to the next one and when it reach the last one, it is sent to a max video device in the master track.

I want to avoid making references with names, just natural and automatic.

Thanks a lot! :)
