I remember back in the day the staff was thinking about having a held item that would have the poses for all of the crates, orbs and event goodie bags ever released, and it would be sold for orbs.
My suggestion, if the staff still wishes to do this, is to have it divided by years. So all the poses for 2017 crates/goodie bags, then I could also buy a 2018 one, and so on.
I think that this would be easier for the staff because they wouldn't have to update the same item all the time, and you could release it at the end of the year and people would buy it (I think).
If you read this staff and you have already decided not to do it, ignore me lol. This just popped into my head.
