(How) Can I use FutureWindows with standard file open dialogs?

Question

I've been trying to use tomazy's FutureWindows infrastructure (see his answer at Delphi GUI Testing and Modal Forms or the home of the tool at https://github.com/tomazy/DelphiUtils), but would like to know if and how can it be used with standard Windows file open dialogs? They don't seem to be inheriting from TControl, which the FutureWindows infra seems to assume (unless I've misunderstood it).

What I'd like to do is basically to just select a file in an OpenFileDialog which is opened modally by a command within my testing, but haven't yet been able to figure out how to do this.
