Consignment GRN field to be added in MRKO

Hi,

I did consignment GRN and i mentioned delivery note in the GRN document....My mat doc is 500001.

I did Goods Issue from consignment stock with mvt 201 K.....Mat doc is 6000002.

Now when i am doing consignment settlement in MRKO....i am getting my ref mat doc 6000002 ( Goods issue doc) and Invoice document no. (510500168)...That is absolutely correct....

Now my client wants in the same MRKO settlement 2 more columns to be added i.e.

1) Consignment GRN document i.e. 5000001.....

2) Delivery note mentioned in GRN document...

How can i bring these 2 fields here....
