Hey Robert! It’s great that you were able to bring your idea to life on Scade. As of now the platform doesn’t support bulk operations. However you can still work it out with AWS S3 Node (little heptic, yeah), to upload all your files into an AWS S3 Storage and then you will be able to iterate through it via subflow node
Also you should check API connector for Google Sheets which allows you to generate and run API requests with dynamic data from your sheet
