Assigning a different owner to "Other Assets" Based on Input field?

Hello, 

I and trying to understand how I would be able to assign an owner to a newly created "Other Asset" through Process Integration.  I know that you assign the owner by using the {{requester_email}} and {{user-var.email}}. But sometimes the person who is submitting the request isn't the same person who is going to be the owner of this "Other Asset". I originally built a Dynamic Form Rule to add an "Employee" field to these requests. Is there a way to pull this "Employee" field as the owner of the "Other Asset"? 

Is it even possible to pass these fields to the Process integration if they are coming from a Dynamic Form Rule?

        <email>{{What would I place here?}}</email>
