dragging audio clips to A3 & A4

Need to preface my question first. I was an AVID editor for 10 years then went to FCP and Adobe. Now after 4 years, I am going back to AVID. I have an unbelievably easy question I know how to do everywhere else. How can I drag an audio clip to A3 and A4 from source mon? Or, how can I drag audio clip from A1 & A2 to A3 & A4? Don't just say click and drag it. The clips will not go anywhere except A1 & A2.
