Okay so I'm a few years into a game and I have a huge mess of Star Swarm ships just a couple of jumps away from Sol. To fight them off I built a large number of Fighters, but now the Fighters are all focusing on single targets, leaving a lot of firepower to go to waste. They are doing their job effectively enough, killing another Star Swarm ship every 5 seconds, but it's only one at a time. I've tried manually assigning targets to each fighter but it's irritating and the orders just don't seem to stick. So my question is, is there any way to get the fighters to assign separate targets, or do I have to keep clicking the 5-second button for a few hours?
