After using PS for a while now, I'm looking for a way to where when a block is placed, it cannot be placed within a certain distance from any other block. For instance, when placed and activated for a 10 block range, the closest block before it can be activated would be 5 blocks in any direction. The exception would be a block of the same type and already active, in order to stack the range.

What i'm trying to accomplish here is forcing the players to place these blocks in "rooms", instead of it being hidden under some blocks.

I went through all 170+ flags, but didn't see anything that could do this. I could have simply missed it as well.
