iOS Crash Report analysis

We are trying to use TestFlight (standard tool from Apple) for alpha testing of our mobile game built on UE4.
TestFlight automatically collects crash reports from devices of testers. However, they are not quite useful with UE4, because they only include some machine-code-level stack traces, where any method names are replaced with their addresses in memory. There are no logs, configs or save files included in the crash archive.

Has Epic Games team worked on allowing to work with crash reports from players on mobile platforms? Is it possible to include game log into the crash report somehow? Is there a guide for performing symbolication of stack traces in the reports?
