WooCommerce Pre-Orders

Hey with the pre order plugin it only allowed one order at a time can anyone fix the php coding to allow it it do more then one preorder. Well I have it were you can add more then one pre order but puts it as one big order. See I have a lot of pre orders with all different dates like some ship in July, August, September. So I would like a fix to were if someone orders a product in July and August. It comes in as two different orders not one. So I can charge for julys when July comes in then charge for August. Can anyone help with the pre order fix. I know it’s with php coding.
