HISMs with multiple different static meshes or variants

Any LOD, HISM experts?
Trying to get HISMs working for a crowd scene using multiple static mesh characters(each driven by VAT )
But with a single HISM component you can only choose a single Static Mesh to be instanced.
How do you get HISM’s to work with multiple different Static Meshes?

Each HISM component can only ever represent one mesh. If you need multiple meshes use multiple HISM components.
