system-config-printer-udev enables all queues

I have multiple CUPS queues set up, many pointing to the same physical printer, with different forms loaded. My queues are named "3hole", "envelope", "legal", "labels", after the paper I load before I cupsenable the printer.

Since changing the paper in my printer is a manual operation, I tend to accumulate print requests in, say, the "envelope" queue until I have the time to switch to envelopes.

Whenever system-config-printer-udev runs, it enables ALL the queues, which causes everything to print on whatever paper is loaded, probably the wrong paper.

I'm not sure how system-config-printer-udev can detect the RIGHT queue to start - maybe by manual configuration? Should it detect multuiple queues pointing to the same printer and issue an error message instead?
