This is a good suggestion, but as you kind of guessed it's not completely trivial, particularly for the "best" matching choices where the results of multiple attempted matches have to be compared to each other in a thread-safe manner. It's certainly not impossible though. I will open a feature-request ticket for this enhancement. It may be more likely to get into Chimera 2 than Chimera 1 though, since I will have to make changes to the MatchMaker code as I port it to Chimera 2 anyway.
