Exclusive Export of Height Levels

I suggest implementing an exclusive export of height levels, meaning that exporting an image of the building at Level 2 should export only that level without including the underlying levels (Level 1 and Ground Level).

This is particularly convenient and fast when there is a need to build multi-level buildings on VTTs, especially with constructions that have internal spaces where the underlying level is visible.

For now, the process I follow is to have three files:

1. The complete construction.

2. A file with only the surrounding terrain.

3. A file with only the building on a green screen terrain.

I export all the images, then I crop/mask the building from the green screen, and I crop/mask each level from the parts it doesn't need.
