Sounds to me that what you want is what the kits create: Those allow to
roll once, then apply an ability or a bonus according to the roll's result.
Thus the added ability later does not know about randomness, it only knows
about the choice the kit made.
Did you investigate in this direction? Maybe by using this you can archieve
what you want already without need for a new tag.
Hope that helps,
