I know it is possible to replace some comps from the composition window by another one from the project bin by holding Alt and using Click+Drag
But what I would like to achieve is different: I would like to be able to select several comps in the project bin then replace them by another one (reduce several comps to a single one).
Let me explain why: I have an After Effect project that has been declined in 24 languages - 1 file per language (not my botched job). I have to edit every of those movie. But a lot of the precomps are identical. I would like to be able to "reduce" them and be sure they all share the same comps and footages (where no translations are involved).
Does anyone know how I could achieve this easily ?
