Alternate units

[Enigma]

Is there some way, a hidden variable somewhere perhaps, that will allow the display of alternate units below the dimension line? I know I can select in the dimension dialogue box to have the alternate units displayed either to the side or below the dimension text, but I want mine to show below the original text, and underneath the dimension line.

ISO standard (Text alignment) isn't an acceptable compromise?

It might have to be, but I would rather be able to do it as I described above, it's not as crowded looking. On linear dimensions, I can "force" additional notes below my dimension line by adding /X in the text. I was thinking (hoping), that I could do something similar for the alternate units while still keeping it associative.
