How to ban without !bl ...

[burunduk]

I cant ban leaver, because !bl works only on last person that left the game. What about leaver that left 2 secs earlier? If I am not clear enough :
15:04 top_feed left the game volountiary
15:06 iximini left the game volountiary
15:10 !bl leaver
15:10 player iximini was banned on server playdota.eu reason "leaver"

Is there any way to ban player like top_feed?
