Hi EveryOne,
Is is possible to make Group By Reviewer as a default for all the reviewers and Sign Off User. This is because when the sign off user login that there is no way that he can see or filter by the reviewer to see who has reviewed then unless he goes and see history for every item.
And
If a reviewer has Sign Off authority on few items is it anyway that he can see on what items that he has a sign off rights directly from UI.
Did you try clicking on the orange arrow (screenshot below)?
It will open a grouping capability.
If your reviewers are direct supervisors, you can group by supervisor.
