Setting up GPS start finish

ADL2 dash, Manager version 4.51.5.0
Am replacing the BR2 Beacon with the Race Grade M GPS BL V2 using the CAN setup .
I followed the UGT3-0004 PDF for configuring.
My Question,
In Calculations-Lap Time and Number setup-Beacon, can I set the trigger to push button instead of Coordinate?
If so, could someone point me to info or walk me through the set up?
Thanks, Gerry
