Saving Timeline Playables in Play mode

Hello all.
I just wondering is there any way to save timeline animations in play mode.
for example, let’s say there is an enemy that i want to follow a specific way, but animating it is a completely b*thurt. i just want to add a controller script to it and get in play mode do what ever i want and save it as timeline playable. i think about writing a script that saves positions and rotations with time stamps in play mode and an editor script that apply this records for me. but this will be very limited extension, also i dont know how to say a script to get and set data from timeline tool.
is there anything that i miss for saving timeline in play mode, or any suggestions for making this work for me?
