Create copy of timeline asset without modifying reference

Is there currently any way of copying a timeline asset without modifying the original asset?

There are several instances where you may wish to modify a animation track asset at runtime with different controllers or animation clips without it being flagged as changed in version control.

I'd like to have a template asset and then the ability to create a copy which can be modified at runtime without affecting the original so that it remains untouched in our version control.
