Good question! But no, not inbuilt.

However, you could override the Collection class and add say a 
Merge(fromCollection as Collection) method, but you'd need to be careful 
of how you want to handle collisions.

so then you could for example

a.merge(b)

to get "a" now containing the four.

Or, you might look at the Collection.Copy source to see if there's 
something in there that could spark an idea.
