Dial Plan Issue

We are using GotoConnect on Voip phones. 

We use a dial plan to ensure my boss does not get all incoming calls, so it rings at the admins desk first. If she doesnt answer within 9 seconds it goes to his desk.

This works great, however, if the admin answers the call and it is deemed necessary for my boss to take the call, how do we avoid having to wait 9 more seconds of ringing until my boss' line rings?
