Text Tags owner in Zoho Sign

Text Tags owner in Zoho Sign

Hello, 
I am using Text Tags for a document in CRM, I need to complete some details on the document before sending it via Zoho Sign. I have used the text field tag. Is a way to set the person who is updating these fields as the user? 

When I am editing the document before sending, the system defaults to the recipient to fill in the fields and I have to manually click 'Prefill by You' - is there a way I can set some tags up to default to the user (to Prefill by You). 

I have added myself as a user in the recipient list but that doesn't change this behaviour, I still have to select 'Prefill by you'.

Many Thanks
Hayley
