Hi, just to follow up, this has now been added in version 2.36.0.
The Enroute Stations option is available at the bottom of the “Alternate Airports” section. Selected stations will appear both on the interactive map, as well as in the briefing package OFP weather/NOTAM sections.
Note that this function is disabled by default, however you can enable it for all future flights by selecting an “Enroute Stations” option and clicking the save icon:
Best regards,
