I like to build automatic tank refilling stations. But, I have to stop the tank, wait until the important stuff is loaded and drive away or else the whole trunk will be completely filled with all the stuff, mainly coal (as you usually have a faster supply). It would be nice to have the possibility to use this button like in the chest to lock slots. And/or like in train wagons having filterable slots (say, you want 2 extra stacks ammo and maybe some spare coal). Especially because tanks are sometimes destroyed.. and all the stuff is gone^^
Just my suggestions
