Applying a split across a building regardless of previous splits

LR

I created a building using vertical splits because some elements (the entrance part) didn't line up with the rest and to keep the number of splits to a minimum. However, now I'd like to split the building horizontally to color its floors separately. Is that possible while retaining the current structure?

Here's a photoshop mockup of what I'm trying to do:

Here's one way to do it:

version "2014.1"

attr floorCount = 4

attr floorHeight = 4

Shape -->

  extrude(floorCount * floorHeight)

  SplitIntoFloors

SplitIntoFloors -->

  split(y) {floorHeight: Floor}*

Floor -->

  comp(f) {side: Facade(split.index)}

Facade(floorIndex) -->

  case floorIndex == 0: color(1,0,0) FacadeVerticalSplits(true)

  else: color(0,1,0) FacadeVerticalSplits(false)

FacadeVerticalSplits(isGroundFloor) -->

  split(x) {

  '0.4: VerticalSplittingLeft |

  '0.2: EntranceOrWindows(isGroundFloor) |

  '0.4: VerticalSplittingRight

  }

EntranceOrWindows(isGroundFloor) -->

  case isGroundFloor: Entrance

  else: EntranceWindows

Entrance --> YourOldCodeHereForGroundFloor.

EntranceWindows --> YourOldCodeHereForWindowsAboveEntrance.

VerticalSplittingLeft  --> YourOldCodeHereForLeftSide.

VerticalSplittingRight --> YourOldCodeHereForRightSide.
