Can RFQ lines be awarded across different rounds in Sourcing

Hi,

We have the following business scenario :

An RFQ  with number 'RFQ-1000' has 3 lines for items (A,B, & C)  & for this RFQ there are bids received from 2 suppliers 'X'& ''Y".

Business decides to award the item 'A' to the supplier 'X' & after negotiation with the second supplier 'Ý' asks him improve his bid price for the other 2 items ('B' & 'C') for which a new round is created & the revised improved bid is submitted by the second supplier 'Ý' for items ('B' & 'C') .

The business requires that for the new round 'RFQ-1000-2' the first supplier 'X' should not be resubmitting the bid for the item 'Á' again & his bid submitted for the first round should be awarded.
