Can you, please, add the option to choose container with items in item White/Black list graphically, like in choosing container in "inventory" bar for programming. For example I put chest to the network, place items in that chest and in item white/black list filter, besides that typing box, there is displayed available in the network chests/inventories. Select chest and finally item. Maybe allow to select multiple/all inventories in the network with items to chose. Alternatively, maybe make variables for available inventories in the network, like player inventory .inv. For examplae .inv1 .inv2 .inv3 ... and for all inventories in the network .invall or .inv0. Sorry my english is very bad, hope it make sense :)
