Relocate CLine using Inches

 From:  Skwerm
I've set my units to feet/inches. When placing a CLine, I can't seem to get it to move by keyed-in inches. For example, I place a vertical (along Z) CLine and then select Relocate CLine and type 2" the line won't snap to that distance. Keying in 0.0833*2 works, but is annoying.

Is there a secret way to be able to key in the relocate CLine distance in inches?
