Card-upgrade to add additional crafting pattern storage to interfaces.

you can already do 54 patterns per assembler, and with interface parts you can put multiple interfaces per block, this request violates #1 and #3

Am I setting my system up wrong then? I have 1 interface surrounded by assemblers. is that not the intended way to do it?

You can do it that way, you can also use 1 assembler with 6 interfaces, its totally up to you.
