Not sure if I understand what you are saying.
What I am trying to do is to display several News RSS Feeds (via API), I have successfully set one source into one repeating group, but having issues displaying several sources.
So what I thought is saving the API call into the database, and displaying this data to the repeating group.
Following this previous issue that I had Difficulties setting up an API End point - Couldn’t get it solved.
So I’ve tried to see how can I put several API into one repeating group in this post: Displaying multiple APIs in One repeating Group, but didn’t get much response as well…
So here I am now 
trying to figure out how to save the a news feed into Bubble’s database, hope to have more luck this time.
