How to record on one track from a specific point

I want to first record a baseline, and then on a separate track add some melody on the piano. I can do this while holding down Shift. Otherwise it won’t record from the start. But I can’t hold down Shift, I need my hand to play piano.

Thankfor for answers!

Change the recording preferences so that recording by default starts on a new track:
