Add Flash-like (Movie)clip behaviour

[Kortenbach]

Is your feature request related to a problem? Please describe.
I'm used to Flash movieclip behavior. The behavior of Wick Clips is quite different. In Flash you have the "Base" movieclip and "instances" of that movieclip. If I change the "base" movieclip then all instances change with it, so if I find a bug then all I have to do is replace the base movieclip and all instances will not have that bug anymore.
In Wick editor it doesn't work like that. If I change one of the clips, the rest doesn't change with it. So if there's a bug in the clip and a screen contains 20 instances of that clip I have to manually replace all instances with the new, bug-free, version

Describe the solution you'd like
I would like Wick editor clip to have the same behavior as a flash movieclip described above.

Describe alternatives you've considered
There is no alternative that I'm aware of.

Additional context
I remember posting a request before, somewhere, but I cannot find it anymore. So here it is (again?)

I think this already exists with normal clips, they're just graphic symbols and movie clips merged into one, anyways.
However, I think that it'd be nice having them separated. Just something I'm familiar with.
