Possibility to change font in Charts for guitar tab

Hello, having the possibility to use ChordPro is great.
It whould be even more beneficial to have the possibility to insert tabs (e.g. how to play a chord or arpeggiated).
One quick way to do so it's just add the tab as a text, but it's needed to use a monospace font.
Or Chords can use a monospace font when there is the tab directive.
