Can this be done? If so, what are the pro's and con's of doing this?
Perhaps it's just me but I can't truly understand your question nor your problem.
Could you please elaborate? Perhaps give an example and screenshots?
The user has created separate assembly files, and now wants to have them all in one file, but as configurations. I have only done assembly with configurations, never trying to back into it by doing separate assembly files into an assembly configurations. The user doesn't want to have to recreate everything, thus the question.
With the amount of info provided by you my suggestion would be as follows.
Let's say that there are two separate ASM files, one being a cube and the other a cylinder.
The quickest way to do what I understand you asking would be to
Do keep in mind that the method that I put forward is the Quick&Dirty way.
In general it's much more advisable to put the extra time and effort in to do it the proper way because it the end the Quick&Dirty way has a tendency to bite you in the ass.
Have a nice one
If the user has two assemblies, they could insert one into another. And then make the configurations that way.
Hope this helps,
