Is the only way to refuel a ship to edit it, and manually fill each tank?
I believe some people talked about using Kerbal Konstructs to handle the refueling, but I'm hesitant to add yet another mod, especially in the middle of a career. I have Ship Manifest installed, and can use that, but it does not subtract any funds for the resources added (and does it instantly), which I'd consider cheating. If I didn't overlook a built-in feature of KCT, how do you guys handle refueling?
