Multiple Line Item approval

Hello. I'm new to M-Files. I hope someone may help me. We have a requirement wherein expiring documents should be added to a request form, like a list of expiring documents. That request form will be routed for approval. In the approver's side, they should be able to choose from the list of expiring documents in the request form which are to approve and which are not. May I ask how can we go about this? Thank you.
