That's really hard in practise you have to make any symbol that selects something depend on the dependencies of the selected symbol. You can't do this without involving a SAT solver. A guy promised to do this a couple of years ago, but the patches never materialised. However, they may exist somewhere if someone wants to take a look at completing it.
