Can I make landmines snap to a grid?

When playing Factorio it seems that landmines are the only object I can place where it doesn’t snap to a grid. I want to make a dragon’s teeth barricade with land mines interspaced but the inconsistent manual landmine placement makes it difficult to cleanly place the mines between the walls.

I tried using drones and blueprints to automate the process but very minor inconsistencies grow when scaled up using drones. I’ve seen pictures of other people who have their mines placed in a grid format, I just can’t figure out how to do so myself.
