RECEIVED PO / MISSING INVOICE #

SUGGESTED

Hello, 

Is there a way to show which PO's that have been received in are missing an invoice? We just switched over from Sage 50 and when the warehouse would receive material in, they would check off the box "waiting on bill". That way I could then just see exactly which invoices i was looking for. There are times in which we will receive in the invoice a week or 2 in advance and i cannot enter that in until we inspect the material. I have seen reports showing "material received" however it also includes PO's that i have already linked an invoice too. Sorry if this does not make sense, I am just trying to figure out if there is an easier way of doing this as we have over 1000 po's. 

Thank you,
