Vertex Snapping inside the Blueprint Viewport

I have a bunch of modular meshes that I’d like to assemble inside a Blueprint to place in my level. I noticed I can snap to vertices inside the regular viewport when just dropping in my meshes there but inside the 3d blueprint network I just seem to be able to use grid snapping.
Is there any way I can precisely snap my meshes together without relying on grid snap inside the blueprint viewport?
