POSTERIZE TIME - set a whole composition in twos or threes

Would be awesome to count with a node that could set a whole “flattened” composition (including all transformations, transparency effects, blurs, anything animated) to be rendered in twos or ones or threes. Similiar to the posterize time in AE.
Right now I think the best option would be to render the whole comp as pngs and then delete, or extend exposure of each frame as needed.

:pray:THANK YOUUU!

is this possible with the new node HOLD-TIMING in HARMONY21??

for what I’ve seen, HOLD-TIMING does exactly that :sunglasses: :ok_hand: thank you TB
