How to add items to the exclusion list

Step 1: stand inside your base
The bulk storage prompt only appears inside a base border. Outside it, the button is simply missing from the inventory screen. Once you know the base layout, our /guides on base building cover chest placement.
Step 2: open bulk storage
Press R on PC, RB or RT on Xbox, or R2 on PlayStation from the inventory screen. A preview opens listing what will move and which chests it will go to.
Step 3: move items across
On PC, right-click an item to drop it into the exclusion list. On PS5, players report pressing Triangle to move it; on Xbox, Y does the same job. The prompts at the bottom of the screen confirm the button for your setup.
Step 4: confirm and stow
Back out or press Stow. Everything not on the list goes into storage, and the excluded stacks stay in your inventory.
Removing an item later
Open the same menu and move the item back out of the list. It will be stored normally the next time you use bulk storage.
