Single line in RFQ for multiple PR

Hi,

Looking for solution to created RFQ having single line which is created by selecting multiple PR. e.g.

PR 01 - Item A - Qty 10

PR 02 - Item A - Qty 15

PR 03 - Item A - Qty 25

in RFQ there should be single line having total of 50 Qty.

At present RFQ creates with three line items as per PR Selected.

In purchase order there is a facility available to have total Qty at line level. we can add multiple PR in delivery schedule tab and all PR Qty gets sum up at line level. If such kind of option is available in RFQ, please share detail.

Thanks
