Dig Instantly with Unity

The logic with unity seems to mostly be "if you can already do it, unity makes it happen instantly." I want that to be the case with digging. For instance: if my bottleneck is currently iron ore production, I could mine some iron ore instantly with unity. Another: if I want to quickly run a water pipe underneath the ground, I could dig a trench, use unity, place the pipe, then mark the trench to be filled. Filling doesn't need to be instant because the materials would need to come from somewhere and that would just be complicated to manage. Also the player would have no idea what the true implications of their action would be unless they already know the amount of loose stuff they have in storage.

I've been playing with coi cheats for the last hundred hours or so, and the only cheat I regularly use is the instant dig/fill. Typically for underground pipes. Instant filling makes it broken because I can just pause the game, instant dig, place the pipes, instant fill, then unity the pipes
