Import data is possible with custom table extensión?

Hi,

The WP All Import is the best plugin to import/export data for WordPress and we are trying to create a plugin integrate with WP All Import. You can try to create the code to import to the custom table, here are some awesome tuts

Any updates on how I can import my data? I have 7 custom tables with up to 100,000 rows. I just purchased the plugin so I know I have 14 days to figure this out, but I was hoping to replace Toolset with Meta Box specifically for the custom table functionality. However, if I cannot import my data, I don't see this as an option.

Otherwise, I love your plugin so far!

I am using wp all import pro but when I import only the title gets imported, non of the custom fields are imported

How can I do this?
