Chord symbols playback duration

Hello everyone, and happy new year.

I've tried for the first time to change the instrument for chord symbols playback and I've noticed that if you use an instrument with a long (or indefinite) sustain, the chord keeps sounding indefinitely until a new chord symbol appears. This is fine most of the time, as that what's normally intended, but if you have a suspension or a section where you don't what that track to sound at all, i.e. by not inserting either notes or chord symbols in it, the last chord keeps sounding indefinitely.

Is there a way to silence the last chord symbol played, or is the only solution to use an instrument with a quick decay, like the default piano?

thank you all
José
