Copper golem doesn't check enough chests

It would be so incredibly convenient if you could have, say, one double copper chest to place for a basic storage system. But no, I have an extremely small and unfinished storage area that the copper golems can't even check the entirety of. Why do they only check ten chests? I'm basically having to go back to manual sorting; these golems are worse than having to make a redstone sorting system. The point should be to put it in a chest and it gets sorted throughout your storage system. Give them a MUCH larger range.
