Code block added to template section possible or no?

Hey Yall,
Most likely an easy YES or NO answer,

I am building a single page website with navigation links at the top that take you to a certain section of the page.

I've seen you can anchor to page sections by adding a code block with:
<div ID="anchor">
</div>

or from the Squarespace Help official video:

<p id="anchor"> Some text you want displayed</p>

but I can't find anyway to add a code block to the template sections I have.

It seems like such a basic and common (used on over 50% of existing websites) feature for Squarespace to not have it available?
Like it would seem crazy and wasteful for Squarespace to run their business like "Build a beautiful website with our carefully crafted beautiful templates... that can't have basic functions like navigation links to them."

But the worlds a crazy place so just checking, am I crazy for thinking that there should be some way to create anchors to template sections or is this just normal Squarespace site builder protocol and the templates aren't really meant to be used that much?

I thought since there seemed to be only an option to add it to pages with blocks that there would be a button that would convert the template to a block version without having to start from a blank page and add back in all the image and text layouts. Is this a thing or no?

Thanks for any answers.
Sorry for my probably obvious questions for anyone with more than 3 weeks experience using Squarespace (;^-^)/

With some sections, eg: Gallery, List Section, you can't add Code Block, you will need to use some code to add it.

In addition, some sections also have anchor ids that you can use
