One of the big problems with the EnderStorage mod is that you have little control over what gets inserted and extracted. For instance, using it to feed a Wither Builder means you have to load it with thousands of items, and then there's a potential of extracting all of one item, and you have to manually reset it.

If the DimStorage chest could allow you to fix the content filter for each slot, that would allow a guaranteed stack of just the items you want to transmit without excess and without the risk of emptying the slot.
