Excavation area selection

Bring back the ability to select the excavation area with a square selection, for example, via the shift modifier. Precise selection of the area is not always required, and moving the handles separately is annoying.

Bringing back the rectangle draw option has been fantastic...thanks, but it would be great to snap it to the grid like it did before Update 3. There are times I want side-by-side set of dumping zones, and it's already hard to draw them due to the way the corners move up and down around terrain. Please make them have an option to snap. Would also be fantastic if (or an alternative to my point here) if while in the edit zone mode, the affected ground would be highlighted.
