Increase the limit on Collection Items

Is there a way to override the 100 item limit on CMS collections. I’m currently over CMS 1000 items and the workaround to keep adding more instances of a collection isn’t palatable. I have 2 main filters (education and inspiration) and 5 sub filters under each of those. It would be overwhelming to keep track of all of those variations.
