Automated backtesting date omissions/consecutive loss #'s


I have been trying to get an answer from search engines and various websites but am unable to verify the existence of these perimeters. I am looking to back test using the built-in strategy tester in MT5, and I would like to omit certain dates(news events) in my back-testing but I'm unable to figure out how to do this, or if this in fact an option. If there isn't an option to do this, how would I go about it? Perhaps I'm just oblivious to the fact. Also, with the data that's collected, again perhaps unbeknownst to me, is there an option to measure the amount of consecutive losses? I would like to have this data as well.

Thank you for your consideration in reading this.
