Issue Title may be confusing, But I would like to see a way to limit not only the amount of items the pipe can put into an inventory, but also how many item types can be in the inventory.

I am currently playing a modpack (Stoneblock 3) and am trying to automate Powah with Pretty pipes (and the storage mod im using). Powah needs to have an exact amount of items for a recipe to complete. The problem is when I request a large craft (something that requires the needed machine to process multiple different item types), the pipes will extract all available items (at 1 item of each type). These items will move into the machine and then stop the recipe from being performed. I have tried using blocks that limit the amount of items stored, but once that block gets emptied and another item input, the pipe instantly extracts it and stops the recipe.
