Detach supporting AI ships more quickly when leader sinks

[sekullbe]

This is more of an annoyance, somewhere between a bug and a suggestion.

I'm playing in admiral mode so I have very limited control over my supporting ship squadrons and divisions. I had a CL (maybe 2, I forget) supported by some DDs. The CL was hit by air that left it crippled and sinking, but very slowly. The DDs stuck around the same spot for hours waiting for that ship to sink, long enough to be hit by three followup airstrikes that sunk most of them. I couldn't find a way to get those DDs to give up and move along

I'd like an ability to force a ship to be abandoned/scuttled, or to force the dissolution of a formation. 

Maybe there's a UI control for this that I didn't see, or maybe I could have detached them somehow?

I requested this very addition a while ago. It's also annoying waiting for a ship to sink when you want to end the mission but the enemy are busy committing warcrimes by pummelling the already-doomed ship. A scuttle function would be great there.
