Ah, sorry I did not realize that you were talking about a user waypoint.
The scenario I was describing is if you would like to add a waypoint with exact coordinates to your route. We support a variety of formats including distance/bearing from a navaid, but here is simple example:
TKPN DCT TKPK DCT 172412N0624718W DCT TNCE DCT TNCS DCT TNCM DCT 180044N0630216W DCT TFFJ
If you enter this as your route, you will be able to add those waypoints as user waypoints from their pill in the top bar like this:
I hope that helps! If you would like a way to enter a custom waypoint directly from the “Custom waypoints” menu, please open a feature request topic in the wishlist section!
I hope that helps! Let me know if something is still unclear, and I’ll do my best to help!
Kind Regards,
Malte
