As far as I know, a box bag is still only push order to a store- it is not available as an SO.
Although not strictly considered "podium" as the SM cannot order a bag in box at Podium, that is when the SM can make their clients ( and their) wishes/wants/hopes made known. IF that is remembered, and the person in charge of bags for your country is then given that information, they are then aware that X store would REALLY like, for instance, a K28 in box. On some level, that then is figured into what is "pushed" to that store ( which is different than the normal shipment that store gets from Paris). In other words, a push is not totally random- Paris looks at what sells where, the store make it known they have a good chance of selling a particular item, and here we are- waiting for our unicorns!

Just remember, it's not personal ( helps put that 5 year or "it never showed at all" wait into perspective)
As to a wishlist? Some countries have them, some do not. Regardless, if its box, and you make your "wish" known, then your SA/SM can make that known to Paris.
Good luck!!
PS- note that someone recently stated in the Paris thread that they were given the opportunity to place an SO at FSH for a box bag, but I don't know anything except what was posted.
