That would work. Alternatively, modify the interactor to have a Set/Get 
Picker method which would allow you to pass in a PropPicker. If you do 
this, I'll test it and check it in for you because I might want to do 
the same in the near future. (It should only need a couple of small 
changes I think - I'd need to look at the code again...)
