Missing VRP

[Vespa]

Hallo...first of all thanks for the great tool!
My question is about Visual Reporting Points...in X-Plane there a re a lot of missing VRPs ( at least in Italy rea), so I have added the VRP coordinates into the custom/waypoints.txt file manually.
I thought that the points would be available in G-Plane since I have rebuilt the database but the VRPs are missing.
Is there a way to make manually added VRPs available in G-Plan?
I'd like to plan and export FMS with VRP available in my GNS430
Thanks
