Ability to manually add levels to queue

Would it be possibly to have an option to manually add levels to the queue so if i find a level when i’m not streaming i can add it to the list?

MultiQueue is a “viewer” queue. You’re not actually adding levels you’re adding viewers. We’re working on adding full support to Super Mario Maker 2 like we had for Super Mario Maker. MultiQueue is more of a hold over while we work on our options.
