alert_when_attack for turret prototypes

[Mooncat]

Request:
a simple Boolean property for turning alert on/off when a turret attacks.


I have implemented a turret that makes no damage but reveals the chunk of the target's location on map. The turret range is quite long. So, it is an alternative of Radar, except it has longer range but only reveals enemies.
The only thing that annoyed me is the alert when the turret reveals someone.

And a quick question, does making the turret range extremely long cause performance issue?

This is already possible: any entity that generates alerts when damaged can have the alert disabled with the property "alert_when_damaged = false".

I know "alert_when_damaged", but it is not I want.
I want to disable the "a turret is engaging the enemy" warning when the turret is attacking the enemy.
