Rename Alerts in Webreports

In my opinion it is useful to use scheduled alerts in webreports to receive some information. If I now create some alerts they are shown in “scheduled activities” similar to
alert 1234
alert 4711
alert 0815
and so on.
This makes it a little bit tricky to search for a specific one. Did I not catch the point where to change the name or is there really acual not option?
