How to map values from EVM Extension Table in BW Profile?

Hi,

In the BW Profile Configuration, at Events> Event Value Mapping only Source Table listed/allowed is 5, i.e. 'Event Message Header'. At Header value Mapping Source Table listed/allowed includes 9, i.e.'Event Handler Header Extension'. Similarly, is it possible to have 'Event Message Header Extension' available for Value Mapping?

Thanks in advance. Regards,
