Change recording menu

I'd like to change the recording menu, to add one more option.

When we are recording something, if we press the REC button again it appears the following:

1 Stop recording

2 Add recording (stop after vurrent event)

3 Add recording (indefinitely)

4 Add recording (enter recording duration)

5 Add recording (enter recording endtime)

6 Change recording (duration)

7 Change recording (endtime)

8 Do nothing

I'd like to have a 9 option = Stop recording and delete recorded file.

If we start recording something, and we don't really want it (we are waiting something special), then we have to manually delete the file.

I've been looking at /usr/lib/enigma2/python/Screens/InfoBarGenerics file , but  I don't understand where to look at.

("Stop recording"), "stop"
("Change recording (duration)"), "changeduration"
("Change recording (endtime)"), "changeendtime"

Those "stop" , "changeduration" "changeendtime" commands, where they "go "???
