Consolidating Line Items From Planned Purchase Order in D365

We are trying to consolidate line items with the same Item Number from multiple Planned PO's with the same Vendor, into one line item for each of those same Item Number lines. This was possible in 2012 and 2009 by selecting group by date or week or month, however in D365 those still come out onto a single Purchase order but in multiple line items and not one single line item as expected.
