Tool which place storage buses. With some modes like decrease priority by n every N until N1 then start with initial value and mb other useful modes. Auto apply storage bus settings like insert only etc.

alternative suggestion

instead of making it specific to storage bus priority, make a dynamic recipe where any blank ae component that has settings placed next to one or more ae component that have no settings configured will copy their settings onto that block. whether in a crafting grid or a specific machine doesnt matter. basically this would be the ability to copy settings like a memory card, but in a crafting way rather than a right click in-world way. then you could use your idea for anything rather than just storage buses.

for example you could make p2ps that are pre-linked to a channel so you dont have to go find the main one every time. and you dont have to carry around a memory card permanently linked to each channel

it'd work, but you'd need the first one in the inv, i want the ability to precraft the first storage bus. But those ideas could coexist. Now i need to find someone knowledgeable on those advanced shapeless craft features to see how to implement this.

addendum to my previous suggestion. instead of ae component with settings + ae component without settings, it'd make more sense to make the recipe be memory card + ae component, and have the settings be copied from the memory card. could be done in assembler or forming press or laser engraver or whatever. then you put the memory card in as a non-consumable.

Could also be added recipes for precraft p2p types? I don't think is already implemented, can't check atm
