Haven't played FS in years, so I had forgotten how much this annoys me.

Every time you target a ship larger than a fighter, cargo, sentry, etc. in Freespace Retail or Open Source Project, subsystem targeting will be automatically activated. That's all well and good, because most of the time you end up wanting to go after a specific subsystem before taking the whole thing down.
However, there are many situations where it causes headaches. For example: scanning larger ships. If you have a subsystem targeted, your ship needs to be pointed towards that subsystem in order to scan. Often this can cause difficulty if you are being chased at the same time (e.g. "Playing Judas"). When subsystems aren't targeted, scanning is much simpler. Just point at any part of the ship.
Also, if you are doing Hull shots with Tsunamis, it is very hard to lock on when a specific subsystem is targeted. Same case as above.
So more often than not, I find myself pressing Alt-S in order to disable subsystem targeting. The problem is, as soon as you change targets, it re-enables!!!
Is there any way to change this through table editing, etc? I was unable to find anything useful in the documentation.
Or maybe I'm the only person who is annoyed by this? Haha, probably.
Anyways, thanks in advance for any suggestions.
