Bedrock Accesories With Custom Skin

I See A lot Of Minecraft Accesories On Bedrock Marketplace Or Accessories that giving free by Mojang Was So Cool, And Good For Player, But Unfortunately these accessories (besides cape) Only apply to the default skin, Not the custom Skin that player make, So maybe mojang could equalize the default skin system and custom skin system to make It same and work with some of the feature that custom skin don't have.
