if the issue is to "identify" symbols which, by prefix, reside in different
regions of the articulated namespace, it could be done on a prefix to prefix
basis or on a region to region basis - depending on whether the specification
has a dynamic or an indefinite extent.
if the issue is that one wants to do that on a name-by-name basis, there are
better ways for that too. one could use a combination of importing and
exporting names among regions.
if the issue is that one whats to articulate the mapping per element, there
are other ways to do that too, though i'm unclear why one would.
