Possible to instance the same static mesh across multiple instances of a blueprint?

I have a project where low draw call counts are critical. It’s features requires an early z-pass and it’s stereoscopic VR those combined quadruple my draw call counts.

For example, I have a blueprint which spawns 10 instances of a static mesh. But I want to be able to use 10 instances of that blueprint. I want all 100 instances to be a single draw call.

Is this possible? Is that what the “Instancing Random Seed” number is for? (if so I haven’t been able to get it to work)

Note: culling isn’t an issue in my case, all instances are always in view nearly all of the time (small items on a table top)
