how to give item org assignment privileges only through item class

Summary:

Hi Guru,

we are trying to assign the item org assignment privileges only to certain users/job roles from manage item class page, but we did not find any actions which can only give the item org assignment privilege without any extraneous ones(like update item attributes, update item categories), could you please help to enlight if it's possible to give a separate privilege for only performing the item org assignment?
