Notification Editor

We would like to change notification subject and body on calls as currently it's an incomprehesible mess especially if forwarding is in place.

Currently our notification shows:

Subject :

New call from <Area or Callers ID> - <Fwd Call group name, ext. number> <number of the client>

Email Body:

From: <Area or Callers ID> - <ext name & ext. number> <number of the client>
Recieved: Date (no problem here)
To: <Actual Number Client Dialed>
Status: missed (no issue here)

We would like to change this to: to simply:

Subject:

New/Missed Call from <Client phone number> to <Client Dialed Number or Ext Name>

From: <Callers ID or Phone Number>
Recieved: Date (no problem here)
To: <Actual Number Client Dialed / Extension Name>
Status: Missed (no issue here)

is it possible to give us some method of editing the default email template completely or at least change the subject line to something simpler.
