Mod request: Mass move order

[Zarquan]

I am currently playing an accept every dupe challenge (no deaths allowed).  Managing my 70+ dupes is hard.  At one point, I asked them to go get more dirt from a far off forest biome, as I had run out locally.  Unfortunately, half my colony decided it would be a good idea to run back and forth from the stable oxygen source and a floating tile of oxygen in the forest biome until they suffocated.  I managed to save most of them, but it was really hard to get each dupe to go to the stable oxygen source.  (Because this was a stupid cause of death, I loaded the game.)  This kind of thing is unfortunately not uncommon.

I was thinking it would be nice to be able to select an area and have all the dupes in the area receive a Move To order to a specified location.
