In the fv3atm, some CCPP physics schemes read per-tile static files. With a global simulation that has a single static nest (tile 7) the nest will read tile 1, which is the first global tile. This is because the model is using tile_of_mosaic instead of global_tile.
Describe the solution you'd like
The atmosphere_control_data should be able to provide the global_tile.

Additional context This is for the Water in the West project, which aims to have a static nest over the north-east pacific within a global model.
