Random order in post grid

Hi,

When making a post grid, would it be possible for you to implement another sorting to the existent ones? In this case, a random order?
This would be very useful for at the moment of “recovering” from the past very useful posts written long time ago that deserve a second chance.
Thanks a lot if you can implement it!
