Can SukiUI display a modal dialog relative to another dialog?

[sethom]

I have an app where I display a ViewModel based, modal dialog that enables a user to edit a record --which represents a request-- before dismissing back to the main SukiWindow. If the user has failed to submit their request when closing the window, I want another dialog to pop up warning them "You haven't submitted your request, are you sure you want to close" with 2 action buttons. If they select "No", I'd like for this modal to close back to the first dialog so they can continue their editing. I have defined this view in a UserControl

I can't seem to figure out how to do this. I have:

ShellViewModel/ShellView
ShellView has <suki:SukiDialogHost Manager="{Binding DialogManager}"/> defined.

I have SukiDialogManager configured as a singleton.

I have a vm called "RequestViewModel" which launches from the Shell as a VM-based suki dialog.

All of that works fine. However, my first thought was to register SukiDialogManager on a per-request basis and request a separate dialog manager for RequestView. When I do this, this breaks the RequestViewModel dialog which doesn't appear. Also, it doesn't appear as if a UserControl can handle the DialogManager

Is there a way to do this ?

Any suggestions would be greatly appreciated!
