Alternate Recipe dependency requirements

I have a mod with many alternate recipes, and couldn't find a way to "gate-lock" certain alternate recipes behind the tires they're unlocked in, for example, in the base game you don't get alternate recipes for Aluminum, until you have access to bauxite, however, atm, for my mod you can get aluminum alternate recipes in tier 1. How would I go about resolving this?

Solution:

Make a schematic that has a dependency on another schematic. Eg. Schematic_Alternate_ElectroAluminumScrap:
