work in compound clip with reference to main timeline

I'm looking for a solution here that I'll compare to After Effects.

There is an option for "keep related items in sync" -- so that when you open a precomp in a main comp...your curser is at the exact same place.

I'm using a compound clip to edit audio and I need reference to the main timeline to know exactly where to do my edit.

How I'm doing this now is trimming the end of the compound clip to the point I want and I see in and out points when I go inside the compound clip. This helps...but it could be smoother.

How about how AVID works with submasters? You can double click a submaster and do editing/trimming inside the submaster while staying in your primary timeline. Anything like this in FCPX?

Use a secondary storyline to do your edits in instead.
