Would it be silly to ask for stackers to handle different materials in each lane? It might even be cool if this was another tier/branch of stacker - or perhaps a stacker that is only one lane wide.
I'm obsessed about maxing out beacons, and especially with stacked recipes, this would make some more optimized designs possible.
I'm assuming this is not possible since an entity can only support one recipe, but it's interesting that stackers already preserve lane assignments for single materials.
