Mine Blocks that behave like Invisible Blocks

[Battlealvin2009]

This may yet be another popular feature suggested before, but could there be Mine Blocks that, after being detonated, will reappear yet again after a few seconds? (the re-appearance time could be identical to the duration of the Invisible Block)

This may be helpful for some Don't Move levels, or maybe adventure levels.

Would be cool if you were able to choose the time it takes to reappear in block options
