Suggestion Box

I know how on items we have the Group Edit Access, where we can set up a specific group and level to be able to edit the item but I would love to be able to set up individuals to be able to edit an item, especially something like an auction or raffle if help were needed. It would save the trouble of having to go through a group, especially since some members don't belong to the same ones as others they may want to be able to edit something. So summed up, edit access for the individual would be suggestion.
