Thanks you so much Tim for your response. I was thinking that I was doing wrong whole day , hence wanted to get it confirmed in the forum.

Unfortunately, modifying the machine learning model is not feasible, so my recommendation is, if this is important to your application, to write a rule-based annotator and add to the end of your pipeline that sets the subject attribute.
