Waypoints and overriding L-points

I was wondering if there’s some way to add a waypoint for, say Eureka. Every time I want to go there I have to select it trough the starmap and it takes unecessary time. Can I just select Eureka once, program the l-points i want to use and then keep it on my contact list until I don’t need it anymore..

And another thing. SOmetimes when I choose to autopilot to one place the autopilot takes me to an l-point at first. This is quite annyoing since I’m sure it would be faster to just go to that place directly. How can I override this?

Thanks
