Question about playback feature

Hi,
Sometimes, specially when recording, I want to wait for a bar (or more than one) before actually recording. What I do is the simple solution of leaving a coule of empty bars at the begining of each track, that way I listen to the metronome for that period of time and then start playing. Does Qtractor have a function to do this automatically? I mean, a playback mode that each time you press the "play" button it plays the requested amount of bars with the metronome only and then starts playing the actual track.
