Helicopter-Routes London - add route names in Charts

I am flying helicopter only in MSFS and love Navigraph for its accurate charts for helicopters.
For the helicopter-routes in London I would like to ask if it is possible to add the names of the different routes.

What I mean is: The routes are added in Navigraph Charts but unfortunately not the names of those routes (H10, H8, H6, H7) - and usually the ATC refers to those names.

As I am flying VR with the inGame Charts panel this does not help me as I always have to look at a piece of paper to check the route names.

Please find attached the official london-heli-route-chart where you can see the different names.
