Adding account segments to GP Web Services "GetGLAccounts"

We recently changed our GL account structure from 4 segments to 6 segments. We are also using GP Web Services to validate an account string.  by call the GetGLAccounts operation.

However the process is only validating the first 4 segments and when I check the WSDL for the GetGLAccounts operation it shows only for segments to check. Any ideal how I can add the additional two segments?
