FYI, economically, this probably doesn't make sense unless you have 10s of thousands of them or more. That being said, if you are looking for a project, go for it!
I assume that the beads are marked on at least 2 'sides'? Otherwise you may have trouble making sure it is in the right orientation. or you can just reject and refeed any that were in a bad orientation. It'll take longer, but probably is an easier solution than enforcing an orientation.
