Keyframe in MOGRT FILE for Premiere

Hello all:

How do I create a mogrt file where I can keyframe a slider control I have in the file? I have a counter that I want to go from 0 to 310. It is for a golf yardage counter called Trackman I've recreated. When I bring the mogrt into premiere you can adjust the value but you can't keyframe it. Any help would be great and thanks. Attached is a pic of the workflow
