Subject's classrooms
For each subject you can specify predefined classrooms in which this subject should be taught - so called "Subject's classrooms". 
You can set it in the menu "Main" - "Subjects" - select the subject and click "Edit" - "Classrooms" - choose one or more classrooms and confirm by "OK":
This feature can be used in two different ways:
1. Every time you add a new lesson, the program will automatically fill in classrooms according selected subject and thus save you effort during entering your lessons. Of course, you can always change these classrooms, if particular lesson requires it. 
2. The second option is to use the button "Set for all lessons of this subject".
By doing so you can Replace or Add classrooms for lessons you've already specified.
