Is This Possible?

Good day all,

I'm not entirely sure what this method would be called but I'm wondering if it's possible.

Is it possible to have a "Mystery Bag" kind of thing on the platform? My thought is; you post a Mystery Bag (items are 'hidden') but once it has been paid for the items are shown so the customer can see what they got inside the 'bag'. Would such thing be possible?

I have never met such addon for CS-Cart or Multi-Vendor. Looks like it is required to create such a module from scratch
