e.g. I add a PSD as a comp to After Effects, but then later find I need to add more layers to the original PSD. I'm then having to import each new layer separately to add it back into the After Effects comp.
It's one of the most frustrating things in a workflow for an animation series I'm working on. Is there a tool on AEScripts which can do this? I assume it's a common frustration.
