Multiple expandable nodes possible in Virtual TreeView?

I am using TVirtualStringTree (part of the Virtual TreeView Component ) in my Delphi project, and I would like to create a view in which 2 columns can have children that can be expanded / collapsed with a [+] sign. In the figure below, as an example, I would like to have a [+] sign in the server column as well as in the image column. The idea is that there are several Server nodes in the tree, each of which has many child processes (the main column of which is an image), and some processes have subprocesses that are children of the process node.
