There aren't any and you'd have to redo large chuncks of code to make it possible, potentianlly including stuff that modders can't access. The best you can do is set up storage next to where you are building, either a warehouse or, if you don't mind mods, my small stockpile (they don't cost materials to build ) and have donkeys transport to there. It still requires humans to move things from storage but it's faster if it's close by.
