Mass Upload "Secured by Worker" users

Content

Hi,

We want to implement Content Zone security using "Secured by Worker". However we have around 200+ workers that needs to be added to the list. 

We are adding the workers manually one by one. Is there any way by which we can upload all the workers quickly rather than manually adding one by one.

Also we have no specific grouping to those workers by which we can search them and all at once to the list.
