Would be nice to add a custom cue with e.g. food symbol or water symbol and text. Use case would be: click on route > add waypoint > drop down menu with icons and a text field to type the description.

In a TCX file it would look like

<CoursePoint>

<Name>Waldstette</Name>

<Time>2025-03-28T22:44:14Z</Time>

<Position>

<LatitudeDegrees>48.77404527272727</LatitudeDegrees>

<LongitudeDegrees>9.81913609090909</LongitudeDegrees>

</Position>

<PointType>Food</PointType>

<Notes>Waldstetten Cafe Stop right here</Notes>

</CoursePoint>

It would be shown on the device like the turn by turn navigation, but only the defined waypoints.
