Auction Manager / >Categories Section . Question.

Hi, nice to meet you.

A summary of my problem.

The first category that I created was ” Domain Names” but , I did not notice that it was the example category of the theme so when I deleted all the examples listing of the website, this category also was deleted but no the sub-categories , ( domain names extensions) that are now multiple categories . You can see it in the photo.

My question here is: there is an option to add this > 700 categories to the new “Domain Name ” category not using a manual process one by one. ?

Thank you.
