Assignment w/ Search List - Icon Controls

-- the add icon can be used to create an assignment for an individual user. This option will navigate you to an assignment screen (without the top section that allows you to search for users -- since you have already indicated which user you wish to add).

-- the multi-add icon can be used to create assignments for multiple users.  When choosing this icon, you must first indicate which users from the list you would like to include (via the checkboxes).  This option will navigate you to a bulk assignment screen (without the filter ability to further refine the contents of the Available People -- since you have already searched for and indicated with users to include).
