Does anyone know if there is a configuration setting in SolPart that will display all menu items in a node up to the root item of that node?

For example, if I have

Root1
   Sub 1a
      Sub 1b
         Sub 1c
   Sub 2a
      Sub 2b
   Sub 3

and I want to show that entire structure as a left vert when I select Root1 and any item w/in Root1 and i want the same effect for Root2, Root3 etc, is there a configuration item that allows that?

Thx,
Tj
