Used item history unavailable from User view

When an item is being assigned to a person, it shows up under "Used items" list in person view, but there's no entry about used items under person's historical view. On the other hand, if an asset's history is being viewed, history tab shows the history of users to whom the asset was/is assigned to.

This would enable to track what has been ever assigned to user during the user's whole GLPI lifecycle, also this would enable a lot easier tracking of assets - for example assets were assigned to someone else by mistake or by somekind of automation mistake. Currently one has to know the asset name/number first.
