NFT Tutorial - creating a 2nd collection

I’m working through the NFT Tutorial (which is great BTW). I minted one NFT on the Rinkeby network and I can view the contract on OpenSea.
I have a basic question. I now want to make a new collection of NFTs and am preparing my 1155 contract. Do I need to create a new Moralis server to host this new collection of images and json files? What I realized is if I use the same Moralis server as my prior “test”, it is possible to overwrite the metadata and image of my prior “test” nft.

Thanks in advance!
