Harmonica Tabs

Does the harmonica app in Musescore have a way to account for the different positions on the instrument? A C note can be played on +1 or +4.
I tried entering a simple tune (Silent Night) which begins with a G note (+6) yet the tablature displayed a +3 which is an octave lower.
The tabs can be changed to be in the right octave but is there a way for the app to do that?
Thanks,
