Why isn't there a donate all button for cash donations.

Just took out 1 billion out of my bank to donate to syndicate and while I was typing the amount into the donate box I was attacked ( I know this is part of the game ) but soon as I was attacked my money was going down making it impossible to donate the cash. My only option was to bank it loosing the bankers fee. A donate all like the bricks and uzi's would be helpful for reasons like this.
