Amazon active workflow is hot garbage

Is there anyway to avoid the d*gshit amazon workflow when uploading inventory and creating a shipment?

In the past I would use the Caleb Roth inventory uploader spreadsheet spits out the inventory loader file and a shipping plan. This would take like 10 mins to upload and I can start labeling.

Currently neither of these spreadsheets work and now I have to download amazons workflow spreadsheet, paste the skus and mark seller for who preps / labels the items and upload to Amazon then spend another 4 hours manually d*cking around in the workflow clicking “NO PREP” category again for all the items multiple times over and over.

Is there anyway to speed this up? This active workflow is hot garbage.
