Campaigns users can use the text field more than once when uploading a contact list. Start creating a contact list through Campaigns > Contact Management > Contact Lists. Upload your CSV file and click 'Next.' Under the 2nd step, Assigning Columns, Toggle on 'Header Row' and then 'Advanced Mode' in the upper-righthand corner.
The third column is Field Type. You can select the 'Text' option. If you add an additional row you can select the 'Text' option again and as many times as needed. You will have to map the column by selecting the box beneath the header labeled 'Map To,' you will expand the box that says 'None' and then pick the correct column that matches this data.
