You are quite right AC3D has crease angle set on a per-object basis, and AFAIK, there is no way round this. I have not found it a limitation - it is a transition value between crease and smooth. Like you, if there isn't a convenient value I break the object. There's no penalty for that - numbers of objects and groups have no performance penalty.
