Nested layouts in Orchard pages
===

I'm trying to migrate an existing ASP.NET MVC 3 website into Orchard, so I can continue to build the site while taking advantage of the extended features offered by Orchard.  I'm attempting to wrap the entire existing site into an Orchard Module, so I can keep all the existing functionality intact, and continue adding features, or porting old features into the new paradigm as needed.

The main issue I'm having with a straight copy into Orchard is that I've taken advantage of the Layout hierarchy in MVC 3 to specify the same parent layout for related pages, which in turn may have its own parent layout, and so on.

When I copied in my existing views, I get the error that Layout is a read-only property on the custom Orchard WebPageView, but when I change the base view type back to the standard MVC 3 base type, the paths do not match up to my views because of the Module folder structure.

Is the ability to specify nested layouts simply not supported for sites running in Orchard, or is there a built-in work-around that I'm missing?

Thanks!
