We have a DMX mover on every fly bar in our venue.  For ease of navigation/visibility in the file we prefer to have the bars at 20m (grid height) instead of 0m (floor) on the Y plane.  

The DMX mover display for these reads 0m when the bar is at 20m and 20m when the bar is on the floor.  This is correcly showing the range of the DMX mover as designed.  But it would be useful to have a fuction to display the actual Y position of the fly bars in meters rather than the offset range.
