As the title says is it possible? If so how?

I suspect it is not and have been looking at alternatives. If its not possible how can I go about overriding a dim by a formula.

Example

actual angle dim = 36°

dimension displayed in its place = result( [actual angle dim] / 360 * diameter )

I have approx 6000 dim to place.

What this is for. The parts are long bent extrusions with holes along the OD. I need to make a print to check the parts. This will be done by laying a tape measure down the part. The ordinate style would really work nicely.
