Let us import a mesh with multiple uv maps so we can swap the uvmap in the texture tab instead of having to import multiple meshes if we want to support multiple uvmap sets. Am sure the performance would improve vastly, I see many products with multiple meshes combined so we can choose which UV set we like (mostly heads in this case) but there's many products that come with multiple UV versions (per example, to support multiple texture placements on the BODY for a BOM tail), thank you.
