R31804 and single-threaded queues...

So, currently we have all our versions of R31804 set up to go to our general-purpose single-threaded queue. Since some versions run for a long time, we want to move it to its own queue to keep from backing up other jobs. I'm pretty sure R31802A needs to be moved to the new queue... are there any other UBEs that might interact with these that I should also move? I asked support this question and got an answer that implied that the answerer didn't know what "single-threaded queue" meant.

My company has setup queues for each type of business fuction. For example, QFIN is for all finance ube's. We have around 10 Queues. This has helped out alot, since one run away UBE isn't allowd to muck up everthing else.
