Production Revamp is a mod that replaces the internal script that manages the production chains, with an "improved" version. It also offers the possibility of creating "recipes" with several input groups (maximum 5) for a production. You can also combine several productions on a single production line. The list of features of this script is long BUT you have to get your hands dirty and follow the tutorial (on this link), to edit your custom production chains. It's a little restrictive but effective if you have an idea in mind (for example the production of a specific food from several entries). If you want to get ever closer to reality, there is no doubt that you will have to go through this kind of mod at one time or another.
