Thanks for your quick reply!
No, I'd like to have it capped at 20 if that's possible. Here is an example:
There will be 20,000 URL's in the URL's column. Eventually I want to filter out specific referring domains and delete them. For example delete "example4.com" and the number in the Number column should update.
EDIT: The ReferringD column would be pulled from the Ahref API.
Thanks for your help!
