Hi there,
It is possible to show the domain name of your websites' pages in your regular pages reports and in custom reports or dashboards, but it does take a bit of extra expertise in setting up filters.
Once you set up that filter, you should be able to see the full URL, including the domain, in your pages reports and when you add the dimension "Page" to any Custom Dashboard or Custom Report.
Keep in mind of course that you can only show multiple domains in the reports for a particular view if they share they are a part of the same property and share the same tracking code.
Cheers,
