How G/L Account code can be prepopulated while Adding freight cost in Voucher Match

Hi ,

I have a business requirements where Customer wants to add freight charges while doing Voucher Match. They will not know how much are freight charges till the time they get supplier invoice. So at the time of voucher matching they would like to add Freight amount in Voucher , which we can manage by Adding OP / match type  4 however they want system to populate GL Account code of Original lines to freight lines.

SO requirement is to account for freight charges in same account as PO Original line & this for both 2 & 3 way voucher match.

Can someone please help in this ? Can this be achieved in 9.1 without customization ?
