Create and manage priorities for a group or project/queue

Would like to be able to customize what priorities are used for different queues. This should be controlled at the queue setup level or by groups the same way custom statuses are able to be organized. Our use case is: our design team uses an array of statuses (low, high, urgent, a custom status 'quick-turn') but our other teams only want to allow 1-2 priorities (normal and urgent). These priorities tie to our overall team's SLAs so it is hard to come up with different SLAs for all of the priority options just because Workfront only allows you to set them system wide.
