Option for different admin emails by event

Just wanted to find out if this is a requirement that anyone else has. Please share your thoughts.

I would like the option to have the email sent to the administrator to be customised per event.
At this stage one can have custom emails sent to the delegate by event.

In my case I need to be able to change the text of the email sent to the administrator for that event. Currently the option is to only have a email message setup globally.
