Control File View Priority

Currently, the view order/priority of models cannot be controlled. If models are at the same elevation, the project team cannot decide which files show on top. An option to set this in iTwin would allow teams to organize their models, similar to how the "Update Sequence" option in OpenRoads/MicroStation allows the user to control the display of references. This is mainly critical for 2D models since they typically all appear at zero elevation.
