Template talk:Theme-stub

Is there a way to add a sort key to this template?
Articles that have this template are automatically included Category:Theme stubs. However there is currently no way to add a Category-sort-key.

I would like to sort all university article stubs under "U". For example Yale University is currently sorted under "Y", while the University of California, Berkeley is under "U". I believe it would be helpful for editors who are looking for University stubs to improve if we had the ability to sort stub categories.

Can we do that? Am I making sense? Thanks in advance, User:Ottawahitech 21:31, 23 November 2020 (UTC)
