How can I import multiple sound clips to the same layer?

I’m over the .mov gripe – I converted my stuf to .wavs.
Now my question is: “How can I import multiple souind
clips to the same layer?” In TBS, you just imported them
via the Sound Editor (right?) I can’t find in in the TBA
instructions. Anyone?

Well you can import the sound files on separate layers then copy and paste the waveform onto one layer and delete the old sound layers.
