Duplicate regions in relation to the last duplicated region

I found this not in a DAW but in a CAD software. In Vectorworks you can duplicate an object, drag it around and then after you placed it you can duplicate that new region. The resulting duplicate will have the same relative position to the second one as the second one has to the first one. The idea is to transfer this behaviour to regions in ardour.
So when i duplicate a region and drag the resulting region around, the next duplicate of the replaced region will automatically jump to a position where its in the same distance from the second region as the second is to the first.
I just think this could be a nice (but not really necessary) feature for ardour also. Of course this should not be the default behaviour but could work with a keycombination.
This must have been horrible to lead. I am sorry.

Maybe this script included with Ardour could help in similar situations?

github.com

Ardour/ardour/blob/master/share/scripts/duplicate_to_grid.lua

ardour {
   ["type"]    = "EditorAction",
   name        = "Duplicate to grid",
   version     = "0.1.0",
   license     = "MIT",
   author      = "Daniel Appelt",
   description = [[Duplicate region to grid]]
}

function factory () return function ()
  -- Get first selected region
  local regionList = Editor:get_selection().regions:regionlist()
  local region = regionList:front()

  -- Bail out if no region was selected
  if region:isnil() then
    LuaDialog.Message("Duplicate to grid", "Please select a region first!",
      LuaDialog.MessageType.Info, LuaDialog.ButtonType.Close):run()
    return
  end

Yes, i think that could do it. As far as i understand it from looking at the code.
I will try that out sometime.
Thanks!
