Project Users, Admin added by default, possible to remove / hide them?

Hi all,
portal admin users appear in every project created in the portal. 
From a users point of view, this can be useful but also distracting: in every page, or dialog, or select list we have the admin users appearing.
Imagining that there is a precise technical reason for this, maybe there is a chance to "hide" the admin users from the various pages. Or maybe you could think about this functionality :-)

Thanks a lot
Andrea
