Spaceship logistics planet filters - add any planet option

[duncanthebard]

So at its simplest, I have a general list of supplies that I want each of my spaceships to have (spare stocks of ammo, space foundations, etc.) each of which is easily avaliable on every planet along the routes of my ships.
However, because of having to specify the planet for each of the imports, my options are to either only have it supply at one planet—which can be fatal during a long route if something goes wrong—or have a different supply list for each planet which seems a huge waste of time and list space in the already very full GUI.
The option to right-click remove a specific planet selction from the 'set orbital request' screen and then confirm out of it exists, but it then re-inputs the last selected planet as a default.
Having the option to remove a specific planet filter, or white/blacklist planets to recieve specific supplies/supply lists from as you would for filtering an inserter would be fantastic, thanks.
