Bank presets are made for you to create setups to quickly gear and fill inventory. Think of runelite tabs, but instead of doing it yourself, it does it for you. The way you do it is type W:ITEMID:AMOUNT to withdraw. To equip type E:ITEMID:AMOUNT
Seperate with commas. Picture below shows withdrawing full graceful and equipping it.
To make this easier, there's a "copy setup snapshot" command, so if you gear and fill inventory, copy it, paste it, and ur good to go for next time!
