It should be noted the scope of the links above is 9 CFR (United States Code) whereas the OP's situation may fall under 21 CFR.

I am not a label expert so I do not know how/if 9 cfr is different from 21 cfr in terms of labeling regs. Enjoy! 
Not sure anyone can claim to be an expert!

9 CFR - Code of Federal Regulations - Title 9: Animals and Animal Products - Not sure what the product is but believe the principle should be the same.
Did review the document you refer to previously:
Food Labeling Guide - Guidance for Industry: A Food Labeling GuideThis guidance represents the Food and Drug Administration's (FDA's) current thinking on this topic. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. You can use an alternative approach if the approach satisfies the requirements of the applicable statutes and regulations. If you want to discuss an alternative approach, contact the FDA staff responsible for implementing this guidance. If you cannot identify the appropriate FDA staff, call the appropriate telephone number listed on the title page of this guidance.The only thing found that may assist was this:
Section 6. Ingredient Lists - Guidance for Industry: A Food Labeling GuideL55. Is it permissible to use stickers to make changes in labeling?
Answer: Correcting label mistakes in any manner is acceptable if the final label is correct and complies with all
regulations at the time of retail sale. The stickers should not cover other mandatory labeling, and should adhere tightly.
