Line Labels (multiple Labels)

[Blammo]

All,

OK, I thought about this some more . . . .

Just as a cheat to get something going, what about just stringing two of 
the labels together, top and bottom of the line, and seperate them by 
some spaces in the text.   This would essentailly give me what I'm 
looking for, but it also has one problem,  I need to be able to figure 
out the line direction.   The address ranges are from-to related to the 
beginning/end of the lines.   Is there a way to tell which direction a 
line is drawn?  I believe the AUTO align does something like this 
doesn't it?

The output would look something like:

   LeftMin       LeftMax
----------------------------->
   RightMin     RightMax


   RightMax     RightMin
<-----------------------------
   LeftMax       LeftMin
