Salvage Beacons Mod
MODPut your settlers to work carrying all your loot back to your settlements so you can focus on saving the Commonwealth.
To Use: Build a Communications Station in a settlement (found under Resources->Miscellaneous), assign a Settler to it, then craft Salvage Beacons in the Chemistry Station under Utility and place one in a container out in the world along with the loot you want to move.
The first method requires you to double-back and walk through every space twice - not to mention you still have to keep running back to a settlement, and the other two are un-immersive cheats.
