If I understand correctly, you want to add you “look” nodes after the show has been balanced, correct?
Would it then be unreasonable to work with versions on the “Track” corrector, for these “look” nodes? After you get the main thrust of the look figured out, you could then fine tune w/ dynamics after you get the OK to proceed… I realize it’s not perfect, but then you don’t have to worry about duplicate projects and extra work…
