Is there anyway to modify body of email alert

Hi all Is there anyway to modify body of email alert ,eg. i mention creating dynamic body which refers subject of the alert mail rather than the custom static message .

 

Currently subject:01070638:5: Pool /Common/pool member /Common/node1:80 monitor status down. body: node is down.

 

What i want

 

subject:critical alert body: Pool /Common/pool member /Common/node1:80 monitor status down.

 

Thanks
