Isolate Properties form different objects in Time line or Dope Sheet

It often happens to me that I need to work with just some particular properties from different objects when I am animating.

In my opinion, it would be really useful if we could isolate those properties temporarily in the timeline, dopesheet, and graph editor so that the rest of the properties don’t show as lines in any of those editors or in the editor we are working in.

This would be similar to when we isolate some objects temporarily in the 3D viewer by hiding the rest of the objects.

This could be done by isolating properties through Ctrl-clicking and then isolating them, or by hiding/unhiding properties. Whatever would fit better with Blender UI conventions.
