Although the effect of the changes likely are widespread, the changes themselves should not be. You should need to edit only three pages to make this happen, or maybe four.
 * 1) template A, to add the  code, or whatever you choose
 * 2) documentation for template A, just to tell users that it does this
 * 3) template B, to accept new parameter and populate the category
 * 4) documentation for template B, just to tell users that it does this

Because only one template needs this, and because that template always needs this, editing the templates is all you need to do. There's no need to edit any of the pages that use template A. Just do what we already discussed, sit back, and watch the magic happen! :-D
