I like using the storage Terminal Interface with Create Vaults; they work well, but once you add an Inventory connector, the terminal displays the items inside the Vault Multiplied by each vault block on the multiblock. Due to that, I need to use the Inventory Configurator to merge the vault blocks into one. The problem is that I can't access the items inside the vault.

Could you make an option so that you can select a wide range of blocks by selecting opposing corners with the Inventory configurator?

This way, I just need to click on 2 blocks instead of clicking on 27 blocks (When I have a 3x3x3 Vault)

Left click with the configurator on the corners

When using the left click, it just selects the corner blocks; the inside of the vault is still unselected. I still need to click on every single block with the left click, and that is the problem I am currently having.
I was asking if it could be possible to have a "two click solution" like how Functional Storage has with their drawer selection tool.
You click on two points, and it selects everything inside those two points.

The "Area Select" is not intuitive. The Inventory Configuration mode is always set to "single block," and I have no clue from the instructions how to set the "multiblock select" so I can add a big cube as the connected inventory.

agreed this configurator is a mess without any documentation at all. I came here searching for some semblance of an explanation on how to use the tool, but unfortunately getting nowhere.
