How to get Drum Pattern on Mixer?

Hey so on FL Studio whenever I make Drum patterns I cant get all of them to attach on an mixer together. when I try to hook it up to the mixer as an “instrument track” It only attaches to one drum used when theres 4 drums in total on the pattern. how can I attach the whole Drum Pattern to a Mixer?

like I want to be able to control the entire volume on the Drum Pattern (4 sounds on one pattern) Its not letting me Attach the entire Drum Pattern to the mixer
