Boundary atuhentication event is to long

Hi there,

we have in the controller.hcl a file sink activated. The activated event types are audit and observation. When connecting to a server, among other things, an audit log is created for session authentication. The request path is /v1/targets/:authorize-session.
The log also contains the attribute “grants_info” . In this attribute all targets from all scopes are listed (in our case a lot). This inflates the log message tremendously (over 200kb and more). Is there a way to configure which attributes appear in a log or to cut out unwanted attributes? Disabling the whole log with a deny-filter on the path is unfortunately not suitable, because the log contains other important information apart from grant-info.

Example of authentication log:

                    },
                    {
                        "grant": "type=target;actions=list",
                        "scope_id": "<scope id>",
                        "role_id": "<role id>"
                    },
                    {
                        "many other grants"
                    }...
