RSS Data Source

I have a Basic repeater that calls in a RSS feed and works correctly on one page. I now want to duplicate the exact process for the datasource creation again with the URL changed slightly. The issue I now have is that I cannot find the data source called CanisUpdatesRSS anywhere within Kentico to clone it. Any ideas on the best way to find it? I have tried searching everywhere that I can see a search tip to no avail. I thought I had used the process for the documentation for External CSS but I have no pages with RSS in the title.
