Then, couldn't we reuse the $UploadPrefixFmt array itself:

# configuration init
$UploadPrefixFmt['MyGroup.MyPage'] = '/storage/for_my_page';
$UploadPrefixFmt['AnotherGroup.'] = '/another_storage/$Name';

# core init
$UploadPrefixFmt['$FullName'] = '/$Group';

with the keys giving the naming scheme to use at upload, and the
related values taken as a sole array defining a search path by itself.
