Hi there, is there a possibility to host a folder on my registrar hosting at the same time as pointing the dns servers to squarespace?

Is there no external tool that can do this?

I'm working on a site where we have made changes to some of the service page urls. Throughout the website there were internal links to these pages, that are now broken as the url has changed. Is there any way to mass change internal links on a Squarespace site rather than going through each individual page and manually changing?
