how to see some keys in the group layer (not all)


i see that when you collapse a group, you can see the keys (move and create too) in the timeline in the group layer. but you see all the keys of everything inside the gruop. this is useful sometimes.
because more than once, i want to move the keys of the head of a character for example (and eyes, mouth, etc) and i cant make this from the collapse layer, because affect all the parts.

i was wondering. there is a way to see in the layer of the group only the keys of what is selected? (like autodesk maya works).

this would do really save much time!

i see in the timeline option the “selection only module” this is not exactly the best solution but really helps!!!

is there another way?
