Create Composition option to include media from current column on selected layers and replace instance on dashboard
Basically, it could function like pre-comping in After Effects. You select the layers you want, make sure the right column is active, and it creates a comp with the media from those layers. It could then optionally place the new comp in place of one of those media clips.
This way, when you realize that you need to compose media that is on your dashboard already, you select it and then choose "Create Composition...", rather than having to make a new comp, place the media in it, then place the Comp on the dashboard.
This command would leave the rest of the layers as-is on the dashboard.
This is now possible in latest beta (so outside the “official” channel, but it will be soon).
