Mapping posts to the primary category (Pre Order question))

Hello,

I am using the free version of your plugin.
I have mapped the categories -> category.domain.com and now I want my posts to have the link primary_category.domain.com/post_title

Can I achieve this with the free version of the plugin, and if not, can it be done with the pro version of the plugin? If possible, could you send me a link to the page in the documentation where this setting is located?

Kind regards.
