Please describe the new feature or change.
Would like to see the option available for furnaces and similar devices where actions are performed on something and the outcome is in conflict.

Please describe why you want this feature.
Furnaces

In my own pack The Seilican Experience at https://www.curseforge.com/minecraft/modpacks/the-seilican-experience a player reported the following issue.

there is a recipe conflict with smelting vile dust and soul glass. both require that you smelt soul sand

If this feature existed in this mod, that would be a great stop gap in the interim.

Implemented in 1.16.4 with the 0.19 Forge release and 0.0.6 Fabric release. The complexity of this feature unfortunately makes a 1.15.2 backport unlikely.
