Tremolo Items Play: On/Off

When working with tremolo items on the "Tremolo" Palette, what they do is totally correct, which is to repeat a note a certain amount of times.
But there are times when we just want to work with unmeasured/uneven tremolo, and that's possible with the "tremolo" text.
However, sometimes we still need the tremolo item image to be written, and I thought that I could just untick the "Play" box in the inspector. And to my surprise, there's no such box for those items (yet).
This would be a very useful feature, since even tremolo in huge amounts causes MS to produce lots of white sound and latency when playing.
Another way of doing this is to create the same tremolo items but without any action. Just like putting a "pizz." text and still play the "arco" sound since it's just text.
