I have seen people using macro to bulk uploading an NFT into it, and also some using Python with Selenium to automate uploading an NFT, I never tried it out so I can't recommend it to you, and especially the latter since it required some coding and need to manually input the seed phrase into the code which it's really risky if you didn't know what you are doing.
Anyway, I think you better move this thread to Service Discussion (Altcoins) board, I think it more proper section and that board are having less spam than this, so the thread didn't keep coming down and maybe others have a suggestion for you.
