Mirroring meshes for tessellating ground cover

A member of my lab is attempting to simulate a coral reef using a dense reconstruction, i.e. a textured .dae file generated from a previous structure for motion setup. Currently we able to import the mesh just fine, as it is a relatively small tiale section.

Going forward in creating larger scenes, we were wondering if it is possible to easily define any amount of tessellation, where we could reference the same attribute multiple times in the world file along with the list axis to mirror across to enable the tessellation pattern.

Short of this not yet being possible, we could just manually replicate 4 variants of the same mesh model into separate files, then load each of the four variants explicitly, however we thought that this may not be as efficient in memory usage given a few parameter and mirroring could achieve the same effect.
