Hello Javor,
Yes, you can restore the selection from the view model.
I've tried to prepare a sample that shows how to do this, but I am not sure when you want to restore the selection. If you clear this our I will think of a possible approach. Anyway, the basic idea here would be to set the SelectedTestId when necessary (as you are already doing).
I also attached my test project, if this could be somehow helpful.
Regards,
