Iron blocks can be turned into controller blocks. Drop the block down, drop a redstone wire or torch on top, switch to the type of block you want to toggle and smack the iron block with it. (Can remove redstone on top after it's been set as a ControllerBlock).
Place those blocks down where you want them to be, you can work from multiple piles of it, where it is in the inventory doesn't matter, as long as you place the block of that type.
Once you're done placing blocks, wack the iron block again and it'll save the block locations and ready to go. Power the block they'll disappear, remove the power and they'll appear again. Invert the control with a redstone torch on top of the block. To remove the binding, just remove the block.
