The Playback Data Dump dialog not retaining values when Shape type Expression is created/edited. A "Dump" works for Text Expressions, but not for Shape Expressions. With today's sound libraries often using keyswitch to change techniques/timbre using the "Dump" playback effect is quite useful. But often a Text Expression with Maestro font does not show the desired musical effect, i.e. Trumpet "falls". So being able to send a single, or multiple "Dump" commands with a Shape Expression would be extremely useful. The alternative is having the keyswitch notes show in extremely low octaves, and even if these are hidden, it creates a very messy score to work with.
