How to prevent overreceipting of large PO's

Is there a way to mark a PO in SAP so that it cannot be receipted for the whole amount?    We have some large PO's that some folks are accidentally receipting for the whole amount and we want to prevent it but don't know how.   'Blanket' PO's can only be set for low-dollar items where receipting is not necessarily required at line item level.   That is not the case here - but we don't know of a way to prevent receipting of the entire amount on only certain PO's.
