We are trying to use the "Underline top line" option located in the Content tab of the Modify MultiLeader Style dialog in AutoCAD 2012 (See attachment).
The minor issue we have is that there seems to be no way to adjust the gap between the text and the "underline". In regular dimensions, there is a dimvar called DIMGAP that controls this distance. Is there any way to control the distance between the top line MText and the "underline"?
