Would like the Raceway label tool to allow me to specify an offset for the elevation properties so that I can label elevations relative to any given floor height.

i.e. First floor is at 3m and raceway at 5.8 will show 5.8 in elevation but user want to see 2.8or 2nd floor is at 6m with raceway at 8.8 it also shall show 2.8

Proposed Solution

I see an "Elevation" and a "Top Elevation" property that can be included in the label which this setting might apply to. We could add another column after "Suffix" named, "Offset" which would be disabled for all other properties.
Note: it shall be possible to add or substract this offset setting from current real raceway elevation.
