Have a 5-bay configuration (206 R2.0) (206 R3.0) (Processor) (206 R 3.0) (Empty) with all incoming lines used. Bought a new (206E R4.1) to be used in empty slot to allow another line to be installed. Want to be able to use this line exclusively for 5 different stations,along with existing lines used by all other stations, and not part of other stations hunt group. On 18 button station , am I able to set this "dedicated line to the upper right most button?
