Persona Animation Creation

Is there any method of creating an animation inside the Persona Editor?

I know there is Record + Add key & Apply, which lets me record a series of motions to the skeleton, but it lacks precision. I can’t even pause the recording.

I can reopen the recording, but I can’t edit anything.

Is there anything that I do wrong? Or there’s something in the core of the engine that stops me from crating an animation in Persona with Matinee like precision?

Or even better, is a future feature?

PS:Sorry for wrong Section
