Feedback against Activity

Apologies if this has already been raised. I always thought it would be useful if you could give feedback against particular activities/tasks in a process as well as the whole process. At the moment I cite the activity number in my feedback if it's specifically against a particular activity - not a huge hardship but can take time when giving lots of feedback! Would also be great if the process map then highlighted the activities/tasks where feedback has been raised (perhaps in the Map view when you click the Feedback tab, it then highlights the activities where feedback has been given).
