Configure component is slow - 168 configurations/70 mates

I have an assembly with about 168 configurations and about 70 mates. When I built the assembly I did most of the work on one configuration only. Now that I am almost done a lot of my mates are suppressed in most the other configurations. To remedy this I have selected all the mates and tried to use "Configure Feature" to unsuppress all the mates in one shot. The issue is that it is taking WAY LONG. I thought "No problem, I'll just do it overnight." It was still calculating and using about 50% of my 8 cores in the morning.

The assembly is way too large to post and I couldn't anyway because of confidentiality policies.

In general, does anybody with assembly experience had some suggestions for getting all my mates working on all my configurations without a supercomputer?
