When creating a new item - "Web Form using Master Page" I get a dialog for choosing the master page.
Can I get that dialog for an existing page so I can change its master page?

No, but you can set the master page by going to the markup and adding MasterPageFile="~/Site.master"
to the <%@ Page
directive
Change Site.master to whatever your master page's name is
Or
If you're in the Page's Markup, when clicking on the <%@ Page
directive and viewing the Properties window - you will see a MasterPageFile
property (Note: this is not shown when clicking on the page name in the Solution Explorer)
you can also change this in the .aspx page, change the MasterPageFile="" setting to whichever masterpage you want the page to use.
