Pasting Special in Piano Roll View

When copying and pasting multiple tracks at the same time in Piano Roll View, I find that I need to know exactly what track to use for the Starting Track dropdown, or all the data goes into the wrong tracks.  I so often end up doing so.  It would be great to know which track should be my starting track so as to avoid this error.  This is often by trial and error.  Could the starting track be bold in the dropdown list perhaps?
