Need expense item level approval/rejection through Approval routing in Expense approvals

Summary:

Business requires expense item level approval. Suppose there are 5 expense items in the expense report which routed for approval. Approver should be able to Approve it at expense item level. If they want, they can reject 2 lines and Accept 3 lines. 2 lines will have rejection details and user can resubmit for approval after the correction as per approver comments are done.

Business Justification: If 2 lines in the expense report are correct and 3 are not, only 2 lines should be approved, and rest of the lines should be rejected. Current expense approvals happen at header level and entire expense report can be either approved or rejected.
