New to Alteryx, so bear with me here
I added an Input Data item to my workflow to read in an xls file and want to skip the first and third rows, with the header in the second row. So to skip the first row, I was looking for the option/setting within Input Data for "Start Data Import on Line #" but I can't see it. This is what I see:

I was going off this forum post since it's relatively new. Where can I find the setting?
If it matters, I'm running Alteryx Non-Admin Designer Version 2018.4.5.55178
