Barré Chord Symbol not editable directly

Hi. When I enter a Barré-Chord-Symbol above the note line from the Guitar Pallette I cannot change the roman numeral that should indicate the position on the fretboard directly. I had to search for a while until I found that it can be edited under the properties panel in the text field (which is hidden by default...!). It would be very useful in my opinion to be able to enter text mode with a double click.

Thank you!
:-)
