Would it be possible to split some of the BLU carnival stages into categories that got the hidden feat vs the ones that didn't?

For instance:

Stage 10 has a hidden feat - Giant Slayer Stage 20 has a hidden feat - Trouble With Tentacles Stage 25 has a hidden feat - Perfect Blue Stage 30 has a hidden feat - The Celestium's Finest Stage 31 has a hidden feat - Pure Azure

All of these feats will appear on the "Stage Results" page if achieved.
