Ability to further edit glissando playback as was possible in MuseScore 3

In MS3, you could change how quickly a glissando changed notes or went through a portamento as seen in the attached image. As far as I can tell, this is not possible in MS4 (or if it is, it's not in the properties tab as it was previously). This makes my trombone parts sound rather strange in MS4 where they sounded quite reasonable before. I imagine this is because MuseSounds has special glissando presets, but for sound fonts it just sounds bad.
