Any way to have a ship cycle its weapons/targets?

That's not really what you want, since you need to breach shields and armor before you reduce the enemy's ability to fight back any.

Instead, try the priorities involving "less than X% damage targetted"
Send enough fire at a ship to crush it, but not too much overkill.

If there aren't any other targets in range, the ships will fire all their guns anyways, just because they can, though
