Using symbol from loaded library to trigger tracing?

[smarr]

Is there any way to trigger tracing based on a symbol that's not available in the given binary, but only becomes available after loading a library?

I am attempting to trace a project that is split into a launcher and a library with the actual functionality, and magic trace doesn't find the relevant symbol.

Thank you
