Repeat Media/Playlists/Layouts in Schedules Every 10 Minutes at Least

I have about 30 monitors with 30 different schedules. Each schedule rotates 5-minute-long media and playlists every 30 minutes, 24 hours a day. If I want to change one of my playlists to a layout in every schedule, I'd have to hand select and change all 2,160 items. I'd like to be able to repeat media/layouts/playlists at least every 10 minutes per day rather than only being able to repeat media every day.
