User's Choice: Add-On Item

Hi, Community! Wondering how people add on marketing materials, club gifts, etc, to User’s Choice Clubs. I don’t add to the package, because I don’t want Club Members editing out their Club Letter. So what I’m doing in the end, is sending our fulfillment house an edited spreadsheet containing the quarter’s letter (and sometimes gift) rather than having them download everything straight from ShipCompliant. Would much, much prefer to include the parts in Wine Direct, as some kind of shipment add-on parts. I think this is more of a feature request?
