Runtime Mesh Component

Hello,
is it possible to add Collision to a MeshSection which use a different VertexBuffer?
I have 2 VertexBuffers the first is for visuals and the 2nd for Collision only, so it does not need to be drawn or need Normals and Stuff.
At the Moment i create a 2nd MeshSection with that 2nd Buffer and set it to invisible. But maybe that is slower…
