Dear Alberto, It looks like one can already do this, although its somewhat obscurely documented. Here's a link to the documentation of the CommonInputs class <https://www.dealii.org/8.5.0/doxygen/deal.II/structDataPostprocessorInputs_1_1CommonInputs.html>, wherein you can find a documented example of computing some solution and cell dependent data. It seems to be a relatively new feature (circa 2016) and I didn't know about it, so I'm happy to have found out about it as well!
