Question Reuse of timelines in other timelines

Hi,

is it a way to reuse a base timeline inside another timeline that expand its behaviour?

For example, in our game we have a default attack timeline that is shared across all units but we want to specialize it to add flavor, so a unit attack could be created using the base attack timeline plus a custom phrase or particles track. That will let us save a lot of time (instead of copy and paste tracks around) with important benefits, like having a cleaner structure and derived timelines will reflect the base timeline changes.
