Well since that is a template modification, why not just edit the template further, and move the code where you want?

I want it on 3 different themes and dont want to edit all 3 lol

In the time you spent asking here, waiting for answers, then implementing whatever is suggested etc you could have made that template edit three dozen times. Honestly, you're wasting your time (and ours, too). Just edit the templates, what's the problem?

If I wanted to turn the template mod into an addon then I would need to know how (if possible) to do what I asked. I'm not doing it just for my benefit.

The template system is hierarchical. Make your template change in a parent style, your additional styles should or could be children. :)

I understand that but they are 3 different styles and nowhere near the same.

Then, why oh why, don't you just use https://vborg.vbsupport.ru/showthread.php?t=152931?
