RFx response create contract with all accepted items

I created a RFx with 3 items. I accepted the 3 items from the same vendor.

After to accepted RFx response, I selected the first line and press “Create Contract”.

System created contract number but the system insert all items accepted from RFx response in Central Contract.

It would be possible to choose the items that would be sent to the contract and the items that would be sent to the purchase order?

Thanks.
