Can an ASP.NET TreeView expand upwards instead of downwards?

[i<3tomodmyvbulletin]

Can an ASP.NET TreeView, when you click the + sign be made to expand upwards instead of downwards? So that "Children" nodes appear above their "Parents." Essentially I want to logically be taking what would normally be a singular leaf node, making it the root of my tree, and making what is logically it's Parent into a Child Node on my Tree, but have that Child Node still display above the Parent when the Parent gets expanded.Think a company OrgChart, but starting with the employee (leaf node) and going up.I can't seem to find anything specifying direction on MSDN. I would like to avoid having to re-write how the Javascript of the TreeView works, but would be open to it if no other way is possible.
