Purchase Order sent automaticly after a quote is awarder

Hi,

A client wants to stop a purchase order from being sent automaticly and wants it to be in status "in Preparation" to be able to amend things after quote is awarder to one of the bidders.

The customer doesnt wants to use an approval process and withdraw it from approval which will send it to "in preparation" as this will make it hard for the person creating the purchase order.

Is there a way or a mistake or a missing info that can be reproduced in the RFQ to make the PO go for in preparation and then the missing info can be amended which will give the customer a chance to ammend his PO before sending them?
I tried on the IRA system but could not find a way around this problem

Regards,

Rabah
