Aliased/grouped domains

[Blizzke]

Sorry if this was asked before but I can't seem to find it right away.

Could it be possible to add alias domains? Imagine that you have a domain.com and a domain.countrycode and a domain.somethingelse, but they are for the same product/company/... Could it be made possible to alias/group the domains into a single block so that every alias action is automatically repeated on all of them? They wouldn't even need to be shown individually.

I have a number of these situations where I like this control and was wondering if that is a possibility.
