Sorry for the delay, sometimes things get away from me. I don't think we have any built-in functionality for this, but I assume it would be relatively straightforward -- I suppose all you're doing is reading in the cryptomatte image and generating a new image where colors are randomly (that is, hashed) assigned to each value of the data you're interested in (object ID, namespace ID, material ID).
