Yes, you can list Modifier Item IDs in a test Barcode, but keep in mind the system will treat it as a Base Item and assign a price point to it.
So if in reality your Modifier typically has a price point of $0.00, it is not recommended to use Test Barcodes when testing a campaign that is specifically targeting modifiers.
Instead, it's recommended that you use the Test Qualification Criteria option in the Qualification Criteria set up.
