Easy process for updating User's activity exemption status

'My Activities' shows a list of Event Programmes a User is registered to. It would be very helpful if the User's exemption status and completion date could be set by Admin within there. Currently it just gives the option to 'Set Due Date'. This would be quicker and easier than having to go via Learning > Manager > locate the Event Programme > find the User > remove their existing exemption date > add a new exemption date
