(I’m aware that Save for Later and Favouriting is a thing.)
There should be a feature that allows you to search for a certain mission from planets that you’ve already explored before, provided you can remember the mission name. It’s meant for convenience.
This feature will allow you to search for a specific mission from places you’ve already explored, just type in the mission codename. Well, it’s not all that useful, but at least it can save you some time and fuel if it counts.
Otherwise, here’s an Alternative:
This feature will allow you to search for missions in the Star System/Constellation you’re currently in, provided there is at least one explored place in the current Star System/Constellation you’re in. Just type in the mission codename. This will save you some time and fuel, but not as much as the former.
