Row level security for internal users and external users

Hi  All ,

Is there  possibility to  show  same report  to Internal users and External  users  in 2 different levels using row level security ??
Here Levels means ...if the internal user is login then the report has to show for full  level  and if external user login the report has to show different level 

Example : country >>state>>district> total sales
If the internal user login the report has to display   "Country >>state>>district>> Total sales"
If the external user login the report has to display  "District>> Total sales" using rowlevel security

Thanks
