None that I'm aware of.
Damage Con is mainly used to reduce damage.
Putting out Fires or Floods reduces damage.
Repairing Rubber or Engine Breaks can help to move and reduce damage.
Clearing a Ping should ideally only be used when it'll reduce damage.
There are players which feel clearing a ping should be done immediately, which is not correct. Much like saving DCP for when you have 2 or more Fires active (to make good use of it), you should look to save your DCP until the incoming torps are spotting. Make the decision at that point to see if clearing a ping matters or not. If yes, then use it. If not, than don't use it.
Being Pinged is similar to having "Priority Target" show someone is aiming at you. People will aim at you all game long and DCP cannot change that.
