Workaround for now:
Create a new layer, insert video router grabbing your comp, add slice transform fx to layer router, add text block to a layer below and label it to your liking, play layer block and update video routers thumbnail, delete text block.
Rinse and repeat the above steps (minus creating a new layer) and then just map your video router as if you would your slice transform fx.
iiiiinteresting!
I totally understand that flow. Funny, I'm also trying to consolodate / collapse my layer count... but this might be worth adding another layer for.
I had someone build me a Max 4 Live device that works as a radio group / Matrix , and that works. but this is even more visual!
i like.
