Ability to specify which UV channel to bake with on mesh import. eg. UV0 or UV1 etc if present

The ability when creating the project or reimporting a mesh to specifiy which UV channel to use for texturing/baking. Our techical dept has set up engine shaders that use UV1 for masks created in substance painter using baked data. The current workaround of exporting a seperate bake only mesh with the UV1 moved to UV0 creates a large amount of extra mesh files and can become hard to manage.
