Apparently this Idea has been done a long time ago.For us this would be
a feature that solves our current problem with our agencies and their
accounts.More and more Critical Data is inserted into Adobe Analytics
and agencies should only have access to the visitors that are generated
by this agency (SEA, Display, Email, etc..) Currently there is no option
to limit an account based on a segment.Limitation-options are only
"variable" / "event" based. Hope this can get a "under review" status.
