Would like an option to allow multiple clothing stacked on the same layer. While this of course would produce an odd looking character model in CC3/CC4, the idea is to export this to Unity where I can save the individual clothing pieces into resources and then programmatically add/remove them to the model for an avatar customization system.

Without this, the only way to do it is through some ridiculous workarounds.

I understand CC3 is probably not being worked on further (except for bugs/minor issues) so if this can be a feature in CC4, that would be great as well.
