Well then, no matter what route you take you'll have some difficulty. There really is no way to ask a pharmacy to restrict narcs if you believe you're going to need/use them in the future. It's kind of like saying "Don't fill this unless I tell you I really, really need them."
Worst case scenario, you can lift an allergy restriction yourself, or your doctor can. Any other "red flag" would likely be permanent. However, expect some raised eyebrows if you present a narc script after listing them as an allergy.
