Making 3D a Print Option

For rooms not to appear rendered in 3D on the proposal, each room has to be deselected on the Room screen. At the point the user realises they have 3D rooms attached to the proposal that they don't want, it takes ten taps (for a two-room plan) to go from the proposal, into the Room tab, deselect the rooms for 3D presentation, and go back to the Proposal screen.

If the Show Default Wall option is not selected in main settings, the 3D rendering will not appear in the proposal by default, but some users want the walls for thickness, but don't want them for 3D. Would it be possible to have 3D rendering be an option on the Proposal screen, the same as the option to attach a plan?
