Thanks for working on this. Please add test coverage and I'll be happy to merge it

@macisamuele, ready for review. Thanks!

Running tests on the pr now. Later today or tomorrow, I'll fully review the changes even though I don't suspect any dramatic changes to be requested (if any).

Thanks a lot for contributing to the project.
