Keep a video source on top, regardless of a switch of presets


I’m just wondering if it’s possible to keep a layer on the screen even once you’ve switched presets?

I’m looking to capture a darts match. Player 1’s board is on Preset A, and Player 2’s board is on Preset B. When Player 1 is throwing, I switch to Preset A, and when Player 2 is throwing, I switch to Preset B. Nice and easy.

I’d like a very basic graphic to be on the screen at all times, regardless of which preset is shown on-screen. The graphic would be a scoreboard, and it would be slightly problematic if I had to manually add it to each preset, because I think I would struggle to perfectly align the image.

Thank you!
