For some Action sets including the Cancel action, there is a Transition drop-down that allows you to go home, the problem is that only applies to Mobile...
Taking inspiration from other Web frameworks where you can define routes to have names, and then apply redirection based on the route's name. I believe now that we can define pages in Portals (Channels and Interfaces). It would be nice to have a new redirectToPage("home") action set where you can provide the page name as a parameter.
