Retail ID question

So in some of the states I deal with my company will have a new package ID for every case. in Ohio we had at least 1 buyer threaten to not order if we didn't start doing it the other way like all cases end in 02 instead of one being 01 02 03 etc. Now we got a message in NJ that if we didn't move to retail ID they would stop ordering. I am a fan of all the cases having the same package ID if the testing data is the same. Does retail ID make this even worse and every package is unique? NJ was on my radar to try and get away from the unique tag for each case will this get in the way of that?
