i can already copy and paste on pc.On PS4 I copy the system on the route planner site and paste it in the galaxy map using the remote play function. I use my Ipad for that. Very easy.
I still have to ctrl+c from the plotter
Open galaxy map
Select the secon tab
Select the search box
Paste the system name
Click target system
Exit the map
Even tho it's easy, i could still use a one click solution.
(or even better if frontier would allow manual plot mapping, but i doubt that will happen)
