Is it possible to create a master page which selects another master page?

Question

I have a master page with name MasterPage.master.

Now I want to create another master page (MasterPage2.master) that its MasterPageFile is MasterPage.master, But when I create MasterPage2 and then create a webform from MasterPage2, there isn't any ContentPlaceHolder in this webform.

Please explain for me...

What you're looking for is nested master pages.
