T4/T5 Transmitter Contact Person

Under the Transmission Information section, there is a drop-down menu for contact person on T4 and T5 (maybe other slips too I presume). Currently, the drop-down shows Preparer, Signing Person, or Other. Could a fourth option be added for Firm Contact - we want provide the same firm contact on all our T-slips regardless of who prepares it.

Thanks.
