I don't think there is, but figured I would ask...
Is there a way to specify that a particular plan has build/agent priorities over another plan? For instance, if I had a "testing" plan that could be launched by our engineers to compile and test their product at any time. This potentially could be queued for awhile. But if I had a "Product Release" that was kicked off, potentially i would want it to have a higher priority over the other "non-important" builds that could be occupying our agents. Ideally it would be next in line to use whatever agents it needed in order to complete it's build.
