Hi,
there's two options.
1) you could modify your step to run as a loop, and then flick through a list of strings to compare, or
2) write your own custom step type. This would involve making a piece of code that took in the list of strings to compare against, and how you wanted to compare them, and then return a pass / fail or whatever you wanted to use for a flag to say how the comparison went.
Have a look at the following URL for more information on creating custom step types.

Hope this helps
