Adding labels to CSV contacts PRIOR to uploading

Question:
This should be so easy. Why can’t I add a label column to my CSV contact file then upload to WIX studio contacts? I have a ton of contacts and want to keep them separate but nothing I’ve read makes that straightforward.
We should be able to add a column in numbers or excel, save as csv, upload to WIX studio and have that create a segment or labelled group.

Product:
Wix Studio Editor

What are you trying to achieve:
I have different contact lists for different email campaigns. I want to be able to send only to one segment or another, not all contacts at the same time. I have read through countless WIX Studio forum contributions and no one makes this simple.

What have you already tried:
forums, google search, wix help, asking a friend.

Additional information:
I can’t get over how this very simple feature is not available and seems to have wasted the time of many wix users. (many, many topics on this forum with the same issue)

You can add a label per csv - so you will want to organize and split up your csv and import each with it’s associated label.
