I am making an NFT collection using Solana Metaplex candy machine. Here, I want to release the collection in 8 categories . So when I release the collection, the user are eligible to mint throughout any of the 8 categories. Each categories are going to have 500 assets assigned. Like for example, the assets are uploaded in this manner:

Cat A: 1-500,  
Cat B: 501-1000  
Cat C: 1001-1500  
Cat D: 1501-2000  
Cat E: 2001-2500  
Cat F: 2501-3000  
Cat G: 3001-3500  
Cat H: 3501-4000 

My question is how to arrange all the assets in such a manner that when the users mint, they are able to receive the NFTs from their particular bracket?

Let’s say, when user 1 mints an NFT from Cat C, so they should only receive the assets between 1001-1500.

In my candymachine, I have although added the labels to add the different categories. But I know, that when I am going to mint it, it is going to assign random assets for the NFTs that I will be minted.

As of now, my candymachine roughly looks like this:

          }
        }
      },
      {

          }
        }
      }

      }
    ]
  }
}

Can someone please help me how to work here? I am going to upload the assets via IPFS on pinata.
