Thank you Markus, I tried several methods like d.extract, or d.where | v.what map=zonpi test and extracting cat values from the test file. Now I am wondering if it is worth (let's better say realistic given my skills) to try and write a custom module, inspired from v.digatt. As I already had a

Yes. That's the idea. Martin Landa already has tried to implement this to some extent in the new wxPython GUI. But it involves a lot of workarounds for inadequacies in the GRASS vector querying. These updates to querying modules would make this easier and more robust. Michael Nice,
