It is easily doable by bookmarking the place you want your ship to warp to and changing the text “Asteroid Belt” with “Locations” in bot.elm. Then you have to change the menu entry text as well (found in the lines below “Asteroid belt”) to the corresponding menu entries (check the appropriate entries in-game).
Due to how the Locations menu is sorted, the first two entries are always unclickable, is there a way to ignore the first two?
