LEAD/ CONTACT OWNER when ADD to CRM

LEAD/ CONTACT OWNER when ADD to CRM

When we convert the Contact in SOCIAL to CRM , it does not allow us to choose the LEAD / CONTACT owners , but most of time, it will automically assign the PORTAL ADMIN as owner.

Am I missing anything in Setup or it works this way ? Is there a way to choose owner or at least the person whose chat or handle the Customer from Social Zoho should be the OWNER
