Modifying source tables from Power BI odata feed

Recently one of my odata feeds changed when new tables were added and I had a hard time figuring out how to add those without deleting my original data source. It turns out you can do so with one simple trick. Just edit the original data source and copy the link and then add a new data source with that same link. 

It will re-use the credentials that are stored for that link and allow you to add the new tables to your dataset.
