Attribute process owner

Hi all, 

Please can someone help - do you know how can I put in the attribute of process model process owner instead of person responsible. And how to translate it also in different languages. We are creating process owner as a new attribute but than the users in Designer cannot see it. Is it possible just to change the naming of the existing person responsible to process owner

When this process is published in Aris publisher the process owner should be also visible

Thank you in advance

Lubo
