Adding on Ambaire's comment, maybe it could be like the scanner where you right click and drag to choose a tier. I would also suggest having the same for other machine types. Mk. 2 miner and storage, for example, as well as different wall and conveyor pole options. Keep everything in radials so you don't have to go into the menu to select each thing you want to make when it's just a different version of what you're already using.
