Possible in backend (just uses JSONSchema), but need to do some trickery with yup and the schema builder in order to allow optional/null numbers for certain fields. Since the value is "", it converts to NaN and trips the validation stuff.

This is really low priority because I seriously doubt we'd ever even need optional fields, let alone optional numerical fields
