No.
Its precisely because it’s a comp/animation package that you’d expect this kind of functionality.
(though afx is rarely used for comp these days)
For example: inserting and removing time to the world track in the 3dsMax Dope Sheet is trivial.
And you have can cascade that to children or not as you see fit. A dope sheet where you can work with keys and blocks of keys would be awesome.
Sure you can be dismissive and say use another tool… or make a bit of noise and submit feature requests.
After this long it seems like a glaring omission in the toolset.
and while were bitching about basic features missing from after effects… How about a link constraint?
so you can swap parent layers during an animation….
