Question Creating Timeline Playable Asset from code

Hello.
First I'm sorry if this is in the wrong thread. I don't know If I should put this to Editor Scripting or Timeline
I'm trying to automate a process for creating timeline with activation tracks. The idea is to have the designer to create a list of gameObject and the time to activate/deactivate each. From that information, I will create a timeline playable with activation tracks corresponding to the activate/deactivate time. So the overall flow is:
- Designer creates a list of game objects with activation time.
- From the list, create corresponding activation tracks for each gameObject in the list, with activation and deactivation time.

The step that I'm curious is that if I were to create the playable asset alone, I still need to load into a Director, then manually drag and drop gameObject into it. Is there a way to automate this too?

I don't have a lot of experience with Editor Scripting. Can someone give a general idea?
Thank you very much.

 

Thank you very much.
Regarding actually creating the PlayableAsset, as I read on the documentation, there are also PlayableGraph and a few other things relating to creating a PlayableAsset from code. As I mentioned, I don't have a lot of experience with Editor Scripting. Where in the documentation should I read to know how to actually create a PlayableAsset and save it in a specific folder (and also delete them if the designer wants)?
