WPF/MVVM: TreeView structure from one ViewModel, check state from another?

Question

I have a tree structure to be displayed on a WPF TreeView. The tree structure is shared between multiple parent ViewModels, but the check state will be different for each.

Is it possible to make the TreeView use one ViewModel to create the tree nodes, and the CheckBoxes contained therein refer to a different ViewModel/whatever to determine the check state?

Hope that makes sense...
