::As you would expect, the tricky part is making all the tag links work.  I had it all figured out, and was even ready to point you to a working example, see religious leader by year.  However, good thing I checked, it turns out someone recently modified the  template so that it automatically adds Category:.  This means that if you tag everything as {{subst:cfd|Umberella}}, you now have to name the section header Category:Umberella, instead of the Umberella that used to work before. Oh well, I had to go back and fixed my links.
