Avoid that file exisists message?

[Biff]

When I save a playlist by pressing CTRL+S, this is shown ("The file already esists"):


When I click "Yes" (Ja), the cue file / any file is not overwritten but a new playlist file is created: Gino Vannelli - Nightwalker.cue.aimppl4

Can one somehow avoid that message when there is no file which will be overwritten? And can the playlist automatically be stored without the cue extension in the name?
