Hey @cobyeastwood183, I appreciate the issue. However, I am a bit unsure what exactly you would like to see implemented here.

Could you please describe the concrete problem you are intending to address with this new capture function for backtraces; that is, could you explain why you need to customize how Sentry collects backtraces in the first place? This will help me understand whether we should even implement this feature in the first place, if an alternative solution might be preferable, or if there is an already-existing way to achieve what you are trying to do.

Also, please describe what you would like this hook to look like (in particular, how you envision the API), so that I can tailor the implementation accordingly should we go that route.

I would appreciate if you could update the issue description with this information, then I will be happy to get back to you.
