Feature Request: Extra Reverb option in Frozen Parameters

Currently there is no way to freeze whether or not Reverb is on or off without also freezing all the Reverb settings as well.

Instead of having just a "Reverb" checkbox in the Frozen Parameters window, it would be great to have two settings: "Reverb Active" and "Reverb Settings" instead.

This would allow me to turn Reverb on and off from the keyboard itself but still preserve the individual reverb settings of the various instrument presets.
