Improvement: Voice message for remaining distance to the end of the route

[Libreporfin]

Hello, first of all, thank you very much for this amazing app for planning and following hiking routes.

 My suggestion for improvement would be to include an option in the audio notifications to indicate the remaining elevation to reach the destination. Just as there is already audio for the remaining distance, it would be great to have the option to hear the remaining elevation gain during the route. Thank you so much!
