Am I old fashioned? Tangent Wave

I have been colourgrading since the days it was invented and one of the biggest features I use is 'grade bypass'. This is very helpful when doing very subtle changes and switching between grade/ungrade to verify the settings.
Using Color's 'ctl G' is a pain (but it works!) so I tried to program it into the Tandem Wave panel and it doesn't have a setting for it... or... maybe I am missing something?!? It would be so helpful having a single click grade bypass function.
Currently I have programmed a function key for 'next grade' and another for 'previous grade' but I gotta remember to put the grade back to where it should be before rendering! At my age thats a challenge!

What would I do without the 'UNDO' button!!!!
