So that's a solvable problem (although it /may/ require a one-time manual config to set up - not sure if it can be automated). I'm not sure if Activity Monitor knows how to obtain symbols from a custom source. So there's a chance an outcome is "sorry, you have to use Instruments if you want symbols." The decision to strip Nightly builds does not come lightly.
