The github links explain how to develop and/or change L18. But, basically enabling developer mode - create a airport scenery project and add this xml in the C:\MyFSProjects\L18_GPS_18\PackageSources\Scenery\airport-l18-fallbrook\scenery\ folder. - then build

To make the sim recognize create a folder in the community folder with the json files and the scenery folder with the .bgl file.

The default for this airplane in the sim did not support GP or VNAV below the FAF and the APR button would not arm. Now, you just hit the APR button and a lower altitude selected and GP will activate to the threshold. Pretty close to the real thing.

I hope this helps someone. There was not a lot of info out there.
