Can I Send More Than One Show to My Apple TV?

Hello Gals and Guys -

I have, I believe, the latest generation of Apple TV HD along with a 2018 Mac Mini running MacOS Ventura. I sometimes beam Mp4 files to the Apple TV from my Mini. It seems I can only do one file at a time, but I would sometimes like to do more. This does not seem to work. I can merge the files in QuickTime with their own tabs, but only the first files appears to play, so is there a way to send more than one file to the AppleTV? Thanks for any help.
