Assigning Users to Tasks

Assigning Users to Tasks

We created a custom Change Control process using the Request to Change template in ServiceDesk Plus.  After initial approval of the Request and assiging a Change, we move it to a Task Creation status under Implementation.  The Requestor is responsible for entering required tasks and notifying the users who need to perform them.  However, we cannot assign Tasks directly to the user, only to User Groups.  

I'm using the User Roles functionality and Change Workflow to allow for notification to specific users when Tasks are created and approved for implementation.  However, they still manually need to find the tasks, and if it's not a user from the Change Template, they need to be added to the roles for the Change in order to be able to view and edit the tasks.

Is there any way to assign specific users directly to the tasks?  I feel like if they can be given edit and closure rights, we should be able to find a way to directly assign them as well.

Thanks in advance for any advice!
