What works for me:
Make independent play-back staves, and ‘filter them’ from view in page/engrave view. Mute, or direct your ‘visual’ staves to a dummy instrument that makes no sound.
Sometimes I only need a couple of articulations that require key-switches at the same time. I.E. Arco in a top voice, and pizzicato in a bottom voice, with both on a single divisi stave. In this case I’ll just make an exclusive pizzicato stave directly under the original as a fresh new player/instrument, copy the pizzicato notes to it using the ‘special paste’ feature, then use select filters to grab and mute the lower voice pizzicato notes in the originial stave above. From there, I’ll go into Engrave Mode, then ‘filter’ my special pizzicato stave. Once it’s filtered, it shows up in galley view, but goes away for page and engrave view; meanwhile, I can hear the proper pizzicato sounds during playback.
