recording multiple tracks

Is it possible to record on Audacity and save the tracks so as to be able to return later and add more tracks to a previous recording?

Yes.

If you have an existing track and you Append Record (Shift-R), a new track recording-right-now will be jammed onto the end of your old one.

If all you did was press Record, you would get a new track recording-right-now underneath the existing one.

If you File > Import a new track made somewhere else, that track will appear underneath all the others.

Audacity does not support Append-Import (yet).
