How to customize AS2 Messaged-ID and filename in AS2 header

The AS2 connection between our company and the partner is OK,and the transaction is also can be sent or received. However,the parter required we customize the Message-ID
and have the filename contained in the header. I have the AS2 raw data transmited zipped as attachment for your information, the file named AS2_File_01.TXT is the format we transmit now, the file named AS2_File_02.TXT is the format that our parter expect to be transmited.Could you tell me how to customize this ?
thank you.
