Fortification building needs inpovement

When digging a trench you have to be in a specific spot in order to dig in the intended area. The build range needs improvement alot of time you have to be inside of a grayed out wall just to build it. Building upwards while prone or crouched almost never works. You have to be inside dirt mounds to build them instead of shoveling from a distance af at least 1 to 2  meters. Digging on the 90 degree  side of a sandbag wall doesn't work if your behind the wall so your forced to exit cover in order to build the fortification in many cases. Building sandbags on top of dirt half wall requires you to be on top of the mound to build in a lot of cases and you cant build it if your prone or at a lower elevation when crouched. Also when building a sandbag wall next to razor wire the wire or wall is prioritized over what fortification your pointing at.
