put page in <main> tag

[wb_user]

hi
I have a design with layout grid
try to put All of layout's in <main></main> tag
The end result will be:
<header></header>
<main></main>
<footer></footer>
but I cant good way to add ~10 layout grids in one main tag
I can set <main> each layout grid. but this not correct work. for SEO, pages should have one <main> tag.
so this question happen: is this work possible in wb?

You can use nested layout grids where the outer layout uses the <main> tag.
or use custom HTML where you add <main> to the first grid and </main> to the last grid.
