Barcode scanning of OTC meds into home med list

It would be nice to add OTC meds to a patient's home med list by scanning the bar code. There are so many brands/companies that make Calcium/ Magnesium and Zinc or Tylenol (i.e. Tylenol, Tylenol PM, Tylenol Cold, etc. ) in various strengths, it would be great to be able to pull the NDC/UPC info from the bar codes, when we have them bring their medications in with them, to make sure we are getting the correct supplements added the patient's med list.
