I see there is a command for cycling torps?

What does this do? At first, I thought you could move torps around from stern to bow, but thats not it. Does it let you say in the bow, move the torps from tube 1 to 4 around?

If so I could see that would be useful if you had various types loaded, hate to waste a homing torp on a small merchant, when it should be sent at the DD climbing up on you instead.
