Run test on a particular request instead of all requests in a folder

I have a post man collection with a folder and a bunch of request urls in it. I would like to run test against a specific request url with different url form data from a data file.

When I run using either newman or the test runner the test is run against all request under the folder. Is it possible to just select the particular request I want to test against ?

TestFolder
/GETURL1?params
/POSTURL2 body {params}

so if i have a data file that has test inputs for URL2 above how do i specify that?
