I can't say for sure but my guess would be no. I believe the ID works in the first case because the stellar isn't changing, so although the system changes you're still landing on the same spob because that system includes the same reference to the spob. There is no way for systems to link specific ships like spobs except through pers. So the system that you use for a mission is the only one it will see regardless. But like I said, I don't know for sure. It would make sense to be as you say but it may just be a limitation of the engine. I'd guess that since most missions involve landing or destroying ships in specific systems at specific times the feature wasn't deemed necessary.
