Sophisticated Backpacks have an upgrade for Backpacks called **Advanced Deposit Upgrade**. Having it installed allows you to hold your backpack in your hand and Sneak-Right-Click an Storage Controller to deposit everything in your backpack to appropriate stacks, but it needs to be configured properly.
+**Important**: You don't need to have this upgrade installed all the time: you can swap it in when making a deposit, and out when you're not using it (it'll keep its settings).

1. When you put the upgrade in your backpack's upgrade slot, you'll get a new tab in your backpack screen with settings.
2. Make sure you change the button to **Match Inventory Contents**; otherwise, you'll need to manage what gets deposited manually, either by tags or list. This means that if a storage container (Barrel/Chest) has a stack of the item, the item you're depositing will be stacked appropriately.
