Qn: Clearing of Automation

in Deluge Help
I know you clear automation with SHIFT + Gold Knob.
However, can you clear all automations for a specific clip with some shortcut or at one go. Use case being you mangled deep and just want to revert to the original sounds. To revert for the entire original track I suppose you just reload the track.

Hitting undo will delete all automation done since hitting record. But there’s no specific way to clear all automation in a clip.
Like you say, you can always reload the song. Save often! :-)
