Randomizing Collection List with 1 item

I’m using CMS to randomize the background of my hero section. I have randomize set in sort order and am limiting the results to 1. Apparently it’s limiting to one and then randomizing, not randomizing and picking the first one like I want it to. Does anyone know how to get around this? I’m thinking allowing it to load the entire collection and using some other magic to hide the rest…
