Any way to make duplicating symbols with animations inside easier?

Hello.

Is there a way to duplicate symbol and all symbols that are inside?

For example i have symbol with some animations inside done on timeline (another symbols with motion tweens)

Now when i duplicate the symbol that includes this content I have to duplicate every single symbol inside and then swap symbol in each keyframe to the new, duplicated one, and only then i can start alternating the content of this copy, without alternating the original "main" symbol aswell.

Im doing this pretty often and it takes so much time... Is there some way to make it easier for people working mainly on timeline with animations?

Thanks in advance.
