I think similar behavior can be achieved by adding custom pages
Blog Dashboard => Pages
This adds the newly added page as a tab next to the Home (also can be ordered by setting page-priority)

Only Catch is - the tabs won't take you directly to an external link. Pages provide space for adding additional context, external links in this case
Each page can have brief info and an external link to the actual site
For Reference, Danny Steenman's About Page - an intro with links taking to social platforms and few more
I am not sure if this works for you, would love to see Hashnode team's thoughts on this
