I am working on setting up a site using Toolset Types and creating relationships between the post types. As of now, I have 2 relationships with 3 different post types. I am testing to see if the CSV Importer plugin will be a viable option for uploading large quantities of information, but it needs to be able to import multiple relationships. I have been referring to the article I linked below on how to do this. I was able to import one post relationship through the CSV Importer, but I need to import multiple relationships (2). Do you know if this is something I can do, or should I request the feature from the plugin developers?
With the above Doc all relationship types (one-to-one, one-to-many, many-to-many) examples are given and as you can see you need to select "Import each record as" where you need to select your specific post type.
I strongly see this as a feature request for the " WP Ultimate CSV Importer Pro " plugin. Please check with their support.
