ASP.NET Dynamic Data - Custom Pages for derived types

Question

I am able to create custom pages for a base type, but not for any of its derived types.

I have a Product class and derived types LightPipe and CardGuide. I created a custom page under CustomPages/Products/List.aspx. This work fine; Dynamic Data uses the custom page when displaying base Product entities.

However, when I create a custom page for LightPipe under CustomPages/LightPipes/List.aspx, Dynamic Data still uses the standard page template under PageTemplages/List.aspx rather than my custom template.

Is this a limitation of Dynamic Data?

Thank you for your time.

EDIT: Added clarification.
