Option for single-click Hands-Free Mode

I like to put the transcription tool into hands-free mode and just dictate. For some reason, holding down the hotkey robs some of my brainpower. So, my default is always just to put it in recording mode. It would be great if I had the option to just click the hotkey once and put it in recording mode, and then again to turn it off, instead of the double-click. It's a little thing, but it would be nice.
