How to customize EWA template in SOLMAN

Hello,

I've configured the "managed system" to integrate the SAP EWA into the Alert Inbox. It works well and generate alerts in the inbox. However is it possible to configure the incident and/or email notification for these alerts? It seems that the EWA templates doesn't work like the SAP templates which I can create custom templates and customize. Does anyone has the similar experience?

Thanks,

Jerry
