I know that we can do this using a band (to show the diffence of elevation between two profiles).
However, when I am creating or editing the layout profile, I don´t like to look at the band data, so I would like this method:
This is the Istram Ispol software, where I can label the difference elevations between 2 profiles in the same profile view in a frecuency of 10 meters:

We can use the Inquiry tool to check this difference elevation in a particular station:

But I prefer show the labels inside the profile view. I think that it is a better way.
