Character Creator items should be compatible with uploaded skins (Bedrock)

Uploaded skins in Windows 10 Edition should be able to have 3-dimensional character creator items added to them in the dressing room. It already asks you when uploading what dimensions the arms are, and the items are always placed on the same place on the skins (the body of which always have the same dimensions), so adding it on to uploaded skins wouldn't be a big step. Another tab would have to be created, allowing the user to add whatever 3-dimensional items are compatible, like hats, wings, etc... This would allow more customization and would benefit the sale of Character Creator items. I have a skin that I made myself and I would personally love to be able to add some of the 3-D character creator items that I have to it.
