zoho recruit - converting all client contacts to candidates

I am currently using zoho recruit and crm integration to import all crm contacts into zoho recruit client contacts and curious if there is way to convert all of my zoho client contacts into candidates? Or bypass the client contacts and import all crm contacts into recruit candidates? I figured out how to do this one at a time but I need to turn all of my client contacts into candidates and that will take forever doing it one at a time. Thanks
