SPG/Tank Destroyers fixed angle of attack mod or option?

Is there an option that shows where your turret’s angle of attack stops when turning?

I’ve started playing more and more early destroyers, and I find it annoying that I can’t figure out EXACTLY when I can no longer turn the turret. I would have liked an indicator, or something red, that shows me the zone up to which I can traverse the gun and up to which maximum turn.

You ask why? I want to be able to preemptively rotate the tracks to aim, because right now it sometimes happens that: you aim at an enemy, you think he’s within your turn range, he’s not, you turn a bit more — that’s about 1-2 seconds wasted on turning the tracks and the hull. I want to reduce that.

Mind you, this is at the extremes of the fixed turret’s angle — I don’t like to move more than I have to, since I use binoculars.

My tip in this situation is:
Turn the hull while aiming every time, the two speeds (hull+gun) add up and you effectively rotate the gun faster and get your aim on target faster. Works for all tanks.

But in general, no there isn’t really a good way other than learning at what angles your gun is limited compared to details on your hull, like if there is a lamp, weld, hook, etc at which the gun stops. That way you have a rough estimate on how to position the hull preemptively.
