Staccato in abbreviations

To get proper playback, put the normal staccato on every note that needs is as though there were no tremolo (abbreviation) on it. Any notes where you do not want to see the staccato select. Click the first and shift + click the last. Right click the staccato and choose Select all similar elements in selection and press V to make them invisible. It's best to make the staccato invisible on the notes that will get the multiple dots also.

To add the multiple dots, select a note and press Z. In the search box start typing "tremolo" until you can find the dots you need and double click them. Click the X to close the master palette then press alt+shift+e to put the dots in edit mode (you may not be able to see them at this point) then use ctrl+ the up or down arrows as appropriate to put them in the correct place. Press esc or click an empty spot to exit edit mode.
