Cannot add web form to project with output type class library

[studio60podcast]

I have a solution I inherited from previous developers that includes
web projects whose output type = class library. I need to add web
forms and web user controls, but when I try to add them, it wants to
add the .cs file, not the aspx or ascx files.

How do I do this?

Thanks!
Jason

By the way, this project already contains aspx and ascx files, so
apparently it can be done...
