How do I add custom 1/1’s and randomly mix them into the collection?

The folder should be named "@custom" with @ and all in lowercase. Then on the Studio tab, select the green “Add Asset” button to add your custom 1/1 with custom name/traits. Your Custom NFTs will be part of your collection when you generate it. They will be in the same order you defined and at any time you can use the "Shuffle" button on the Generate screen.
