Using custom tags

Hi
I am a UE4 user and we are not integrating the Sentry SDK into our game. Is there a way for me to define some custom tags without using the SDK ? I am using the UE4 example to configure the tags but they do not get recognised by Sentry. For example doing something like this : config->SetStringField(“configuration”, “Development”); In this case configuration is not accepted by Sentry. I could overload the tags already in used by sentry but I would like to define my own tags to help us search through issues in Sentry.

I have not found a way to define my own tags. Is that possible ?

Cheers
Pascal.
