Deletion duplicator

[RMS Gigantic]

A particular idea I got while painstakingly improving my massive flag: What if there was a duplicator where it placed the series of bricks, and any brick that gets in the way gets deleted? It would certainly make my replacement work a lot faster and easier, rather than spending several minutes replacing a singe flawed star with a single corrected one by going through, brick by brick!

There are deletion bricks or something that delete the bricks inside of their ghost when you place them.
They come in cubes, I forget who made them though.

I think you're suggesting a brick overwriter or something along those lines.

Yes, I am looking for something that can overwrite bricks in groups. It would be like a duplicator that takes priority when placed.
