Essentially, the Schema Config is at the discipline level, but pick lists are at the collection level. It’s a bit confusing as you need to create a new pick list with the same name in the other collection so it is available to Specify. Even if you can see the pick list from another collection in the schema, a new one must be created for the items to be available in other collections within the same discipline.
You can schedule a meeting with me using this link! It uses my most recent availability so anytime it says I am available I’ll be able to meet:
