Hi, I have a couple of issues.
1. I can't seem to import a custom taxonomy "cars". I used "csv_post_cars" in the column, but nothing happened, the tags just didn't get registered. I also tried this "csv_ctax_cars" as well but this time I got an error stating "Unknown taxonomy"
2. Is there a way to replace "_wpcf_belongs_cars_id" to use slug instead of ID?
