Describe the Suggestion

Allow the player to select which items should pass through a filtered block first.
Allow the player to set priorities for which inventories in a contraption get filled/emptied first.

For example, in an iron processing plant with an automatic input, I'd first want to process blocks of raw iron, then raw iron, then cobblestone. Currently the only way to do this is to set the order of items to be processed in the inventory manually or use individual brass funnels for each item.

Currently the priorities for contraption inventories are beyond my understanding. Having a solution that works the same for a contraption facing in any direction, assembled in any order, etc. would be a boon for creating complex automated contraptions.
