I am looking to setup a collection on the solana blockchain. The idea is that when a real world watch is sold, the buyer receives an nft validiting this purchase with the appropriate metadata (time of purchase, watch details, name etc). However, my question is if it is possible to add new nfts to an already created collection from the same contract as each watch is purchased? Thanks
