Navigation - announce the name of the next waypoint after reaching the current one?

Situation: in my country one can ride bike tours by following numbered roadsigns (see image below) which are positioned along the roads. One can also create tours using a special bicycle route planner website, and download them as GPX files, then import these into Locus as tracks to navigate along.

The numbers of the roadsigns are included in the GPX-file. When using Locus to navigate along the track, and using speech announcements, the number of each waypoint is announced by speech. This is great. However, since I do not know what the next waypoint is without looking at my screen, I have to stop to look at my smartphone. Or I have to print a list of waypoint numbers, and attach it to my bicycle steering wheel. Both ways are cumbersome.

There could be a better way: since Locus already has the "next waypoint" information in the GPX-file, Locus could help out, as follows...

Feature request:

When on a bicycle (or walking) tour, upon reaching a waypoint, I need to know what the number is of the next waypoint to go to. It would be great if Locus would have a setting which allows announcing via speech what the number is of the next waypoint to drive to.

Of course, I could achieve this by manually editing the GPX-file using a text editor, and for each waypoint in the file type the number of the next waypoint after it. And then import this edited GPX-file into Locus as a track. However, such manual editing is quite a lot of work, especially since such bike tours can have dozens of waypoints.

There could be a better way, if Locus could "look ahead" into the track, find the NAME of the next waypoint, and then speak it upon arrival at a certain waypoint.

Would this be possible please? Thanks!

Example:

Suppose the track contains the waypoints numbered ..., 51, 46, 78 ...

Upon arrival at waypoint number 51, Locus would speak "51, next is 46". Upon arrival at 46, Locus would speak "46, next is 78". And so on for the entire track.
