Add email addresses using ADRMAS

Hi,

We need to *add* email addresses to existing vendors. I have configured LSMW with the IDoc type ADRMAS and it works ok, i.e. it updates the email addresses of the vendors. The problem is that it overwrites the existing addresses while we need to add more addresses to existing vendors.

I have even made sure CONSNUMBER in the IDoc is the next one after the existing CONSNUMBER's in ADR6. The IDoc has CONSNUMBER = 002 but it till updates the email address in CONSNUMBER = 001!

Is there a way to tell ADRMAS to add email addresses rather than overwrite existing ones? Or some other IDoc/BAPI?

TIA
