Programatically change Args CustomChannel so it can be dinamic

[alexvazquez]

I have Serilog slack configuration in appsettings.json:

{
"Name": "Slack",
"Args": {
"WebHookUrl": "https://hooks.slack.com/services/xxxx/xxxxx/xxxxxxx",
"CustomChannel": "#dev-log",
"CustomUserName ": "Slack Logger",
"BatchSizeLimit": 20,
"QueueLimit": 1000,
"CustomIcon": ":ghost:",
"TimestampFormat": "o",
//"MinimumLogEventLevel": "Warning"
"restrictedToMinimumLevel": "Warning"
}
}

I need to change in runtime the CustomChannel because in my code depending of logic I should notify to different channels.

` 
LogContext.PushProperty("Environment", environment.ToString());
                        LogContext.PushProperty("UserName", loggedUserName);
                        LogContext.PushProperty("ErrorUID", logException.ErrorUid.ToString());
                        LogContext.PushProperty("SecuritySessionID", sessionUid);

                        // *** HERE I NEED TO SET THE CustomChannel PROPERTY *** //

                        _logger.LogError(exception, $"An error with ID {errorUid} ocurred.");`

Any clue?
