Dear Markus, Many thanks for your help!
An r3.what was indeed what I was hoping for. Is there any chance of a command such as this being developed any time soon? It would be very useful!

You would need a new v.what.rast3d module. Perhaps the code of r3.stats could be helpful for that in order to see how to obtain voxel info (I thought we had a r3.what but that's apparently not the case). > Any ideas would be greatly appreciated! Some programming seems to be needed for this.
