We have several queue's that need to have users only when the user is available. On a normal user account, this would be accomplished by setting a rule with a specific schedule and then changing the users/phones available on the call handling. However, there is no option to remove/add members on custom rules for a queue.

Why is this not available? For instance, if we have only 2 users on a specific office queue, and 1 member will be out on vacation then we would want to add someone else who is not normally on the queue for the 1 week of the original user's vacation. As it currently stands, I have to remove the original user, add the new user, then set a reminder to undo these changes when the original user is back. Am I missing something?
