Apologies if this has been suggested before; I did a search and didn't find anything quite pertaining to this.
I'd like there to be some sort of option to intercept enemy expeditionary forces, particularly defeated ones, and "escort them off the premises," so to speak. By way of explanation, I was recently in-system dealing with some other business when a Hegemony expedition was narrowly defeated by my own forces, preventing the raid but not wiping out the enemy fleet, whereupon it immediately set about harassing and attacking everything it could until I finally chased it down and blew it up. What I'd like to have done *instead* of blow them all up is simply send the remaining forces on their way, mission failed but no hard feelings, and hopefully recoup a bit of the rep lost when the expedition was defeated. I know destroying the rest of the fleet didn't hurt my standing with the Hegemony any more but, for one, I worked up to full positive rep with all the established factions before settling my colonies and I'd like to maintain that somewhat (I understand running free ports means expeditions, that's fine) and, second, I generally like to play good guy types and having no option between "let them keep being a thorn in my side" or "go full Terminator on their asses" didn't quite sit right with me.
Ideally, this would also be an option if you've intercepted the expedition en-route and your own fleet is clearly superior to their own, with a concurrent reduction in rep loss (only 1 or 2 points, say) for the expedition failing. Maybe that option could require a story point.
Basically, I just want to way to be civil about showing unwelcome guests the door without doing so kinetically.
