Xfinity DVR: How to schedule NFL Football to record?

I'm new to the Xfinity DVR having spent decades using TiVo. I used to have a TiVo Wishlist to schedule all recordings on any channel with the keywords "NFL Football" and "NFL Preseason Football" and every program with those keywords in the name or description would be recorded.

I cannot figure out how to do this with the Xfinity DVR scheduling feature. I am only offered the option of selecting each individual team and saying to record all games for that team. There must be a better way!

Please let me know how!  :-)
