Asking for a Workaround: Ability of Line Managers to approve specific goals from a transaction

Summary:

Content (required):

Currently, when an Employee adds 5 goals to his goal plan, then sends it for approval, the Line Manager will only have two options - Approve or Reject. How can a Line Manager approve specific goals, and return the other goals to the employee for edits? Do you have any workaround for this or how does your organization do the approval process? Appreciate any response. Thank you!
