Again, I think I know the answer, but wanted to ask the community to be safe.
I get that with trigger lock you can keep the lock indefinitely until you lock onto something else, use the lock, or have it removed in some other way.
But, a pilot could use target lock one turn, and some other action on subsequent turns, correct? So, a pilot might have an active trigger lock from a previous action AND say their focus or evade from their current action going at the same time.
If so, target lock is a pretty cool ability because you can use it even when someone is outside your firing line to set up a future shot with lots of chances to hit.
