Two questions. One, about cautionary tempos and putting two voices on one staff

  1. Is it possible to move rall. From above the staff to below the staff? I have used the popover. In either the band score or parts??
    How do I do this? It seems to default to above the staff.

  2. I have a March that I am working on with a half note in one measure and in the same measure I would would like to put below the half note an eighth rest and 6 sixteenth notes.
    Is this possible and if so how?
