YOu would need to take photos of each of their different units hashing and would need to at least give their member name a shoutout per order, since you're picking up multiple, it would need to be confirmed for sure that you do indeed have 5 different units for different people shown in the same photograph.  We'll have to pray that 5 different swiss folks have preordered and plan to be hashing and will share their miners to the world come monday or hopefully sooner.
