Remaining vertical distance

Hello,
is there a way to show the remaining vertical distance to the next waypoint or the whole track as an Data Field?
I would find it very useful for hiking, because the time you need is more about the elevation than about the distance. 

There is an option to show the elevation distance between the current position and the final destination, but this makes no sense if you are on a round trip or have a descent in between.
If you navigate and you have the elevation plot open you can already see the remaining climb, but I want it as an Data Field and also to the next waypoint.

Can anyone help me?

Thanks in advance
Markus
