How to replace static mesh with blueprint and proper rotation?

I generated my cylinder within a program called Rhino. The cylinders were parametrically generated due to the surface having a more complex shape. Unfortunately, Rhino doesn’t really have many options to specify how vertices are exported. I may need to bring my meshes into 3dsMax and export from there to maintain proper vertices positions of each mesh.

I thought about the single BP with a static mesh component as well. I was just hoping I wouldn’t have to manually replace every original static mesh with a new one since there will be hundreds of them.

Have you had success exporting proper rotational values of meshes from Max? Thanks
