Hi Merch Pros,
The Multi-Product Uploader is a wonderful blessing, thank you! We've gone from it being a chore to fill up slots to an absolute joy.
Suggestion: Tier-up in larger increments than 2000 slots due to the newfound ease of listing. Perhaps by 4000 or 6000? It's still faster to fill-up those numbers than it was prior to the multi-uploader.
