Ability to add animation tracks on uneditable imported animations

[Tormentous]

Now I don't mean rotation transform or scale animation tracks I mean the ones where they decrease the need for code, for example I import a new model and I want to add sound effects or a call function to an animation without having to make unique or go through that whole process like if I was going to completely overhaul the animation

I insist we need animation inheritance.

See:

• Add animation inheritance #9802
• Add a notion of Inheritance to Animations through Linked Tracks #3858
