@kiranchandramohan @jeanPerier this is the most local solution I could find to apply what we discussed to privatization logic.

I **think** modifying `getSymbolAddress` as Kiran suggested at first might not work since:
- In privatization logic, we need the `SymbolBox` and not just the address.
- `getSymbolAddress` is not used by the privatization logic.
