[GRASS5] 5.1 - Vector data and elevation information

I just tried the new vector modules in grass51. You have done a really good job! Congratulations. It is working very nice.

I have got a question about elevation information on a vector line. Will it be possible to store elevation information on every node of a vector line?

I have digitized some streets in 5.1. Additionally i have some point data describing the elevation information of our region. Is it possible to "merge" the elevation information into the edges of every vector line?

Thanks in advance
