Linking to a blog post page from the link settings

Hey there. I hope I’m posting in the right place.

I can’t find a place in the Link Settings to link to an individual post. The Pages appear as options when linking from paragraph text, just not the Posts.

I’d love to link to them just in case the Posts or folders move around in the future.

Many thanks in advance.
