Assigning Parts to Individual Users

I’d like to know if there is a way to assign a part to an indivudual user. For example, we have items such as cases, cables, or adapters that do not have an individual serial numbers that we want to keep track of and assign to users. We figured using parts instead of assets would be the way to go for this because we have quantities of the same item. If the feature is there I may be likely missing it.
