How to use:
1. Select Bin Prefix and Mod
2. Choose Cross Pick and Start From options
3. Upload your Excel/CSV file (with Bin ID and Bay ID columns)
4. Click Submit → Export to CSV/XLSX
How it works:
• Within each Bay: picks all bins on Shelf A, then Shelf B (reversed), C, D... (snake)
• Facing aisles: 1 bay from first aisle (bottom→top), then same bay from facing aisle (top→bottom)
• "Except first aisle" option: first aisle runs solo, remaining aisles pair up
