Describe the feature

Right now, the partioning of a storage bus only affects which items can be inserted into the attached inventory.

It would be nice to have either an upgrade card or a toggle option for the Storage Bus so the partition works both ways (or maybe even both or either one direction).

Reasons why it should be considered

It would be useful if you want to expose only part of an inventory's items to AE.
For example, if you have some kind of inventory with a very large amount of different items in it, it can take a while for AE terminals to load. A specific example would be Equivalent Integration's Transmutation Chamber, which exposes all of a player's EMC transmutation knowledge to e.g. storage buses. This can easily be thousands of different items in larger modpacks.
