I need help finding a way to use one item give 2 forge materials.

[Akkiruk]

For example I would like to be able to put a piece of scrapIron in a forge and have it add to the brass category and the iron category so I can make bullet shells AND iron arrowheads. (This is not what I am trying to actually use it for. That was the simplest example I could come up with.)

Thank you for any insights into this tricky problem!

Currently, I do not believe that is possible. What you could do is create a recipe for bullet shells that use iron instead of brass.
