Is there any way to selectively run data fro different rows in the data grid

I only have the option to control my start and end

Is there any way to select rows I want to test in this command line or

Do I just un-select the rows? hint hint I found the answer while writing this post

You cna say I just had the Eureka moment

BYW you can run play to see what rows of data is being used and whats skipped.

Now that is handy!

and I found starting row has an index of 0 and not 1!
