Ignore Selected transactions response times in overall gatling report

Hello all,

Is there a feature in gatling when generating a report after a load test, the overall resulted response time will not be contributed by a selected few transactions (eg. file upload request)?
Reason is I would like a report that do not consider the response times of transactions known to be slower that allows me to pass my load test with global assertions of response time >3000ms.
Thank you very much!
