Voucher line chunking - vouchers with hundreds of lines

AP related issue......We have some invoice files that we load with hundreds of lines for one invoice number.  When we load these invoices we find the vouchers are virtually impossible to open up in the voucher panel.  The system either times out or takes several minutes to open.  I know there is a "chunking" feature on journal lines and in other areas of PeopleSoft.  Why isn't there a chunking feature for AP?  Is this a soon to come feature?
