Mark order as "Sample" or "Gift" for Commercial Invoice purposes

Frequently, clients may need to send gifts to influencers or samples out internationally. There is no way to mark them as "sample" or "gift" in ShipEdge to my knowledge currently. This results in them either putting everything as $1 and getting flagged and held at customs or not doing anything and the person has to pay customs fees to clear it or they have to do DDP to pay customs they shouldn't need to pay or they ask us and it's a long process to manually create it in Easypost.
