Issue templates question

Hey all, I have a question with configuring issue templates and how to keep them in sync. What I would like to have is a single central place where all my issue templates live so that I can add new templates as time goes on and have those appear in all my projects. Is that possible somehow?
I’ve gone through the docs a bunch. I’ve created a template project with some issue templates and set that project as my “project template” on my group. That has the effect of pulling in whatever issue templates I already have but now how do I keep everything in sync if I add/remove/edit my issue templates?

Thank you
