Avis car rental question:

I'm traveling with another party who is renting a car with Avis under their name. I'm planning to meet the other party at the rental location, although there is a chance I may not be able to meet them at the rental shop. If I am not able to make it, as a preferred member, do I still need to be present at the rental counter at the time of renting in order to be an "additional driver"? Meaning, being present to sign the additional driver form and show my license. Per Avis website, they don't address this scenario specifically but it sounds like I will need to be despite the fact I am already a preferred member?
