Hello,
What you can do is protect the text and extra then add specific protect tags for cards that have edits. You can see how to protect specific cards only in this post: 🔐 Protecting Fields and Tags
After that, you can unprotect the Text and Extra fields in AnkiHub and do this to receive all the new changes:
Reset your local changes. To do this:
Go to browse in your Anki → at the top click on ankihub addon tab → press reset all local changes
This will restore everything to what AnkiHub has unless you have specifically protected those fields
