Can I change one of the test data slices

So I want to replace the test data with another value so that when it has a hit it will show the replace value instead of the original value from the wordlist. How would I go about doing this?

Put this in LoliCode at the end of the config

data.Line.Data = myString;

where myString is the name of a string variable with the new data line (the full line, not just 1 slice).
