How to update Internal links when moving headers?

Hello, I have some problem updating internal links for headings:

As far as I know, Internal links are only updated when you drag&move files in different folders through file explorer.

However, I encountered a situation that I need to cut-paste a header(and all its subheader and content) from a .md file and put it in a new .md file. All internal links pointing to that header are not working after I extracted the header.
How can I update all internal links in this case?
Thanks!

we don’t support this yet. Search/open a feature request. This will be very tricky.
