Is it possible to use AME for AP Invoice Line Level approval in Oracle R12?

We have a requirement to do approval of AP invoices based on the invoice lines.

For example: if an invoice has 3 lines assigned to 3 requesters, we'd like to send out 3 notifications in parallel for approval.

I'd like to verify the following 2 things in AME:

1. Is possible to setup AME for Payables Invoices that are not matched to PO to route for Line Level approval? We have a requirement to route an invoice to multiple approvers at the line level based on the requesters populated at the line level.

2. Does the AME atribute LINE_ITEM_STARTING_POINT_PERSON_ID also exist for Payables Invoices Approval?
