Burn redeem for blind mint 1/1?

hey all -
I have searched the docs and the forum and haven’t found a clear answer to my question so posting. I want to set up a burn redeem where collector burns x amount (on base or another l2) and then gets a random 1/1 piece of art (on eth mainnet) while supplies last for the 1/1. I found this page which seems to allude that you can do it: Customize metadata for an ERC721 Claim and Burn Redeem | How can we help?
however I’m very confused on how to actually set it up? When I go to burn redeem set up I don’t see options to create more than 1 work to be redeemed for ~~ so can I create a limited supply burn redeem for a 1/1 blind mint? If so, how do I do it more clearly than that article cause I really don’t understand? If not, can it be something sooner than later we could do?

Thank you in advance - I would ideally like this set up before solstice cause I would like to do it as a burn event for solstice which is in a month time from this post.

To setup a burn and redeem the campaign has to be published first! Similar to a claim, once it’s published you will see an Edit menu that allows you to update the metadata in the campaigns’ settings!
