Amadeus II - multitrack?

I love this software. Easy. Fast.
I wish that the multi-tracking was there.
I've just been opening multiple AIFFs in Amadeus to do it.
But you can't play them simultaneously very easily.
So I've just been inserting silence for about five seconds at the start of one AIFF.
I begin playing the one with the silence first and when five seconds are up I start the
other. It's sort of tricky. It would be nice if there was something that allowed you to
play multiple AIFFs in sync. If someone else has an easier method please drop me a
note.
