Forum Post: Adding Custom Coordinate System from Microstation/Map

I have a dty file with custom coordinate systems that I use in all the microstation based Bentley programs, such as Openroads, Microstation, AECOsim, Descartes. This is achieved by adding a variable in the config file to add the dty file into the geographic system library. This creates a new Custom Coordinates folder in the library. How do I make that coordinate system appear in the library of Context Capture.
