Zoney, that's the function of Categories.

Ah, but you see, that's exactly the kind of thing
that would be nice
to stop (in my opinion). If for example, [[Gilbert O'Sullivan]] is
likely to be confused with [[Gilbert and Sullivan]] (and I'm not
certain about that, but yes, there are other plausible examples), it
should surely be treated as disambiguation, not lumped in with a list
of *related* articles. "See also" is too much of a "catch all"
title.
