A Custom Airport page that allows users to store Sim airports not in Navigraph

Hello,
There are lots of airports in a Flight Sim that that don’t appear in Navigraph or with a different ICAO in the Sim. So why not add a page to Simbrief similar to “Saved Airframes” that allows the user to specify their own airports with an ICAO, coordinates and runways etc. and which is also possibly shareable with other users?
Thank you.
