I would like to do 3 different actions and I completely do not now how to deal with it:
1. Send back - which sends the item to previous approver (who already had approved it).
2. Send back to initiator with information that initioator has to update some data in the form.
3. "Consultation" option - person A can send the item to person B (who has been chosen in a field in the form). Person B can only leave a comment and sent it back to A. And now, if desired, person A can send a question to person C before he decides to approve a task... etc.
