converting estimates to supplier orders (QB online)

Hi There.

I am trying to migrate away from my current order management system to QB and appear to have hit a showstopper...

Within our current system we will regularly receive a "request for a quotation" from our clients. These will be for a range of products invariably that we need to source from multiple suppliers and offer on a consolidated quote / estimate. This seems to be achievable through the process of generating an estimate and sending it directly to our customer. At this stage in our current system we can simply accept the estimate once we receive the go ahead from our client, enter our clients PO number and the suppliers will automatically receive their POs for their element of the order. From what I can see in QB we would need to manually create all the suppliers POs resulting in more admin and a real risk of mistakes etc. Does anyone have a solution or recommendation to overcome this challenge. I guess it is also helpful to see a summary of an estimate including the profit and supplier.
