Idea (1.18.2): Inventory Checker checks Chests behind blocks

[Dante-tLDS]

Hello. This idea is to have the Inventory Checker from RFToolsUtility to be able to check for chests that are behind a block similar to how a comparator can. This could mean having an additional option in the GUI to set how many blocks (1-x) behind it it will detect for.

Additionally, this is more of a question, can the Inventory Checker be set to scan for any/filtered item in any slot rather than a single specified one? I can't seem to figure out how to do this,

Other Idea:
To add to this, is it possible to have this scan for all inventories in its range and base itself off of that? Just a small thought.

Playing in 1.12.2 and 1.18.2
