[SOLVED] Mail content for Direct Alert Notifications

Question

Hi,
I asked this question during a 10g New Features course once but didn't get an answer... maybe somebody here can help?
The format (long) of an email notification from EM (10.2.0.3) is:
E-mail Subject (Long Format):
EM Alert: <severity> <target name> <message>
E-mail Body (Long Format):
Subject: EM Alert: Critical: prod1.us.oracle.com - CPU Utilization is 90%
Date: Mon, 14 Oct 2004 12:56:46 +0000 (GMT)
From: "EMD Notifications" <[email protected]>
To: [email protected]
Name=prod1.us.oracle.com
Type=Host
Host=prod1.us.oracle.com
Metric=CPU Utilization (%)
Timestamp=14-OCT-2003 12:57:04 (GMT 0:00)
Severity=Critical
Message=CPU Utilization is 90%
Rule Name=ALL_HOST_METRICS
Rule Owner=MGMT_REPI would like to (drastically) change that format. The emails will be going to a central helpdesk where they will be picked up by people with absolutely no Oracle knowledge, logged as faults and passed to the DBA team. As such I need to present them with a no-fuss, easily understood email - something like:
Subject: EM Alert: <severity> <target name> <message>
E-mail Body (Long Format):
Helpdesk,
The following event has been detected on <name> for <host>:
<message>
<timestamp>
Please raise a <severity> fault and pass to the DBA team for investigation. 
If necessary please contact the on-call DBA.Has anybody ever achieved (or know how to achieve) something similar?
Cheers,
Joseph

Just a further note - this has already been raised as an enhancement request. The following update is from Oracle Support:
The enhancement bug 6155970 was opened in 2007 .
Feedback from DEV is that ER 6155970 is not planned for implementation in 11G.
Bug description.
Abstract: SUPPORT CUSTOMIZATION OF EMAIL FORMATS FOR ALERTS
Many enterprises rely on email/pages as a primary way of getting
notifications for alerts. Many of them rely on the subject line of the email as way
to determine the type of alert.
Thus, it is important for them to be able to:
a) specify the pieces of information about the alert that they would like to
see in the subject as well as the body of the notification
b) specify length to be shown for some of these (e.g. the message of the
alert). This customer in particular would like to have EM show more of the
alert message in the subject line, beyond what it is currently showing.
Solution:
You can use an OS command notification rule and use a Shell script to send customized mail.
The OS notification rules set the following variables to unix schell.
"target name " $TARGET_NAME
"target type " $TARGET_TYPE
"target host " $HOST
"metric in alert " $METRIC
"metric value " $METRIC_VALUE
"policy rule " $POLICY_RULE
"key value " $KEY_VALUE
"key value name " $KEY_VALUE_NAME
"violation context " $VIOLATION_CONTEXT
"timestamp " $TIMESTAMP
"severity " $SEVERITY
"message " $MESSAGE
"rule_name " $RULE_NAME
"rule owner " $RULE_OWNER
