When binding a Revit link it would be extremely helpful to have a "Maintain Phases" check box. This would also require a Phase Mapping dialog like we currently have in Type Properties for Revit Links. I guess this could just be a link to that dialog as the Bind command is working on a link.
Currently all phasing is mapped to the phase of the current view during the bind operation, which makes for big problems - especially for items that were set to be demolished.
