How to add 2 trade names in a single GST registration ?

Sir what if I want to keep only single registration and add new business in additional place of current registration than will it be legally ok to display and use XYZ AUTOMOBILE for business given this trade name is not present in registration certificate ?
 

You cannot add more than one trade name in one GST registration. You have to apply for seperate registration in this case. 

Mam ,what if I want to keep only single registration and add new business in additional place of current registration than will it be legally ok to display and use XYZ AUTOMOBILE for business given this trade name is not present in registration certificate ?

because as per my understanding keeping same GST will help me claim ITC of businesses together .

If I add my new business as additional place ,will it be legally ok to display and use this trade name given this name will be present under  " additional place " & not  under "trade name " in GST registration certificate .
