Multiple Vaadin applications in Grails App

I was wondering if there was a way to add multiple Vaadin applications to a single Grails Application.

It would be nice to be able to assign a particular Vaadin application to a controller/action, or at least a url-pattern in the Vaadin config when it builds the servlet-mappings.

Wanted to see if this had been answered before I add it as a feature request in Jira.

Anyone else had this situation?

I need this too.
