The ability to combine vendor invoices into one.
This can already be done as long as you are setup to separate the receiving and invoicing step. There is a setting named "Automatically generate vendor invoice" that when set to Never or prompt, the system will generate a receipt that can be posted and then when ready, the user can generate the vendor invoice from that receipt. But if they select multiple receipts, they can combine those onto a single invoice.
