if in a node you have more than a restraint

ex: node 20 you have 3 restraints: +Y, GUIDE, LIM

then in isometric you will have 3 separate rectangles indicating each one of the single restraint:

one rectangle containing "+Y"
one rectangle containing "GUIDE"
one rectangle containing "LIM"

is there a way to automatically compact the 3 rectangles, having in the node ONLY ONE rectangle containing the text of the 3 restraints "+Y, GUIDE, LIM"?
