No

this is my list

Thanks Nathan, I had that idea when I was looking at this - but even now I've checked a list from System 5 times. My list is missing front/ global/ global template...

That's what I saw. But there is no option anywhere to add a custom template in the head, ie. this custom template does not contain any code to change or add to the different parts of the site, but only contains a link rel preload, or prefetch - and should be added to the head in site. Or, as in the theme editor there is a Custom CSS that adds inline CSS directly to the site head, so there should also be a Custom template in the theme editor, so that optimization preloads, prefetch, etc. can be easily entered.

Example: I have created a custom template that only contains a link-rel preload for image. This template I want to add before close the head tag in my theme.

How can I add a custom template to my theme head? I created it through theme designer - templates.
