Article duplication desired

TTRSS v17.12, mysql 5.7

I’ve seen discussions on the desire to eliminate duplicate articles, however, I’m working on an application where I would like the opposite behavior. Currently when multiple feeds post the same article I only see the article show up under one of the feeds (I’m assuming whichever one updated first) when instead I want the article to show up in all the feeds it was posted.

My question: Is there a configuration setting I’m overlooking to allow duplicates or do I need to dive into the source code?

Thank you.
