Feature I'd love to see added to instrument filter view

I find the instrument filters in galley view enormously useful when writing. There’s one addition I would love to see to it. Just a little toggle/button that plays back only those instruments currently displayed in the filter would be very helpful.

I know I can currently marquee round the staves in order to achieve this, but having a little ‘speaker/ear’ toggle would speed this all up and streamline it a bit, especially when auditioning more than just a few staves.
