It kinda works like this, a stretch back I got 2 different sets of skins for the Borg. 1 was superior to the other so I updated the 2nd one with components from the 1st. After awhile I started combing thru the numerous skins I played with and getting rid of the ones I didn't like anymore...but instead of outright deleting them I instead assimilated them into the UT Born Collective.
