SecurePRO (ReadyAPI 1.6.0): How to modify the default assertion "Valie HTTP Status Codes"

We run SecurePRO Security-Tests.

Therefore we use all the default scans provided.

One of them is "HTTP Method Fuzzing"

Request: PATCH http://localhost:14080/rest-service/rest/contact/contacts?languageCode=xx

Response: HTTP/1.1 500 Internal Server Error

Now, SecurePro is alerting (Warning): Valid HTTP Status Codes: Response status code 500 is not in the list of status codes

But I can't find any place to modify the list of valid status codes.

Please note, I did not add this assertion manually

It's a default assertion as it is also a default security scan.

Any ideas?

Thanks
