Is there a way to create a Portal that goes directly to a custom page?

Is there a way to create a Portal that goes directly to a custom page?

I want clients to go into a webpage type view and be able to see the details of what we have on file, and be able to update some of those details. 
It looks like Portals only allows the Contact/Build list view. I started a Canvas page, but it still goes to the Contact/Build list view. This is not really suitable for clients who just want to see the info about their jobs. 
Is there a way to do this?
