Adjust Expression Pedal Range 0-100

I have added MIDI capability to an old Rodgers pedalboard that I acquired recently. The expression shoes operate via a 10k rotary potentiometer that is advanced by a lever when depressing the shoe. However the pot only moves through about 90 degrees of rotation, and that is all that Organteq acknowledges - it sees a range of about 33 - 78.

I can change crescendo and swell settings to work with this limited range, but I am wondering if there is any method for mapping or reconfiguring the software settings so it will see this "compressed" range of motion as beginning at Zero and advancing to 100 or 127. I hope that makes sense.

I have played in the MIDI configuration options a bit but am not having any success. The rotary pot has a full range of motion (when disconnected from the linkage of course) and otherwise works fine. I am considering installing 45mm slide potentiometers to better respond to the movement of the shoes if software cannot address the issue.

Prior to the pedalboard I was using Moog Ep-3 pedals for expression, which were very well suited to the task.
