Thanks for your replies.
It is possible to use RX declicker, declipper et cetera as batch processing but in this case I need the spectral cleaning which I don't think is possible to use this way.
It might be better to do it on the mix but RX doesn't handle surround files so it will take some trickery. Also in the best of worlds I like to RX things and then let things like reverb smooth things out a bit.
