Update: My bad! I misread the core of the request and assumed a topic already existed. I’ve now tagged the topic accordingly. My apologies.
Hello Darkhog,
As explained in the Feature Request rules ⭐ Welcome to the User Feedback channel!, we ask people to make sure the feature request doesn’t exists before creating a new one.
I will close and archive your request since Animatable tilemap already exists. 
You can -of course- go to that topic to vote, comment and show your support.
