Thanks for Brians's informative inputs,
Hi Rolf,
Based on my research, this is a high priority feature request which is
voted frequently by community users. Our internal web platform & tools
team has recorded this request and plan to add the nested master page
design-time support in next release of Visual Studio(code name Orcas).
Here is the public request entry on the product feedback center:

kID=103439
You can also vote on this request. As mentioned in the request entry, In
the current VS 2005 RTM version, you can at least specify that the
end-point content page or child master-pages simply define a
masterpagefile="" (empty string), that will still permit you to go to
design-view. However, you'll need to put back the real value for the
runtime.
Anyway, the product team has put high priority on these features(like the
nested master page or global master page in web.config's design-time
support) since these features is conform to the best practices we recommend
to develop reusable and maintainable web application.
If you have any other requests or commens, also welcome to submit in the
feedback center:
