My office has a Hub site with a custom HTML Header. This site was built several years ago and has admittedly been updated and edited multiple times as our needs have expanded. It is in a constant state of growth and construction.
Our issue is that if we make any changes to our site (adding new pages, or changing names of existing pages to match projects) we have to update the HTML code for every single page in the Hub site to make sure all the links stay consistent across our site.
Is there a way to just update the home/main page of the site have have those changes propagate through the rest of the pages?
