Some mechanism to have multiple different, attachable pieces of hair

[qlee01]

Hey, this is probably more like a feature request: currently it seems not possible to have multiple exchangeable and attachable pieces of hair (e.g. different eye brows), at least not if the different styles need to be loaded from a prefab / asset, as I understand the skin attachment system only handles stuff which is active in scene, and does not use any sort of ID to identify a loaded asset to resolve the poses needed for attachment.
Would be great to have some way to store the attachment information per hair asset and load only if needed.
Not sure if this is even a topic for the hair system, or the digital human lib, or both (probably last).
