Linking two embedded views on a form

I’m using an embedded view with an embedded editor on a form. This lets the user select a document in the view and then view the document in the editor. This is working great.What I would like to do next is add a second embedded view with a select single category to show the response documents for the selected document in the first embedded view. Is this possible?

This application is for the ND6.5 and ND7 client only (no web).

Thanks for any pointers
