This would allow a workspace to have a custom dty file that is specifically named for a project, without making a change in the configuration variables, which we are trying to avoid for end users. We are wanting a workflow where a dty file that has an adjusted coordinate system available to be selected for all files, so users do not need to go adjust each file individually. This would be similar to OHDOT, https://tas.transportation.ohio.gov/CADD/OHDOT/Standards/OHDOT%20Utilities/Training/OpenRoads/ORD%20Survey/Guides/OHDOT_ORD_Survey_200_Geographic_Coordinate_Systems.pdf. This would eliminate the need to define dty files as described in https://docs.bentley.com/LiveContent/web/Promis.e%20Help-v10/en/GUID-AAF77C12-776B-41E7-A685-1C12EC8D3154.html and instead be able to search for all dty files within a specified workspace location.
