Compare to schema inside same database

Compare to schema inside same database

Hi,
I started to evaluate DbForge Studio for PostgreSQL.
I wan't to compare schemas inside database. (I mean those schemas which are created by CREATE SCHEMA myschema);  our use case is  for example a  franchising chain, where all companies are under same database with different SCHEMAs. 
I was able to compare to databases but not two schemas under same database.
