Wing Edit missing Load/Save/Scope section for Library-Mixer function

Using a console I can save/load snaps via the console. But Wing-Rack is thought to be used remote. Without the Load/Snave/Scope section, like it is available when a snap is saved via the “Edit” tab, the Wing-Rack is unfortunately not usable. Thats why this is for me not only a missing function but a bug. I need to load different snaps during a show for different songs and groups using different instruments.
