This could actually be classed as templates. You would configure all the items that occur to the entire school/institution and then copy this to the lower levels.
You could have for example, the period 3 on day 2 of the educators master set for a staff meeting, and for the classes, this set as a study period. You would then copy the educator master to the educators and the class master to the classes.
You still the the ability to personalise individual timetables of educators, classes, rooms, subject, and groups.
Configuring these timetables is simply a matter of selecting the required period or periods(you may hold the left mouse button down to select a row or rectangular region), and right clicking the mouse for a pop-up menu of choices.
Once you have done this, you may then copy this down to the lower levels.
Please Note: New educators, classes, rooms, subjects and groups begin with a blank timetable and do not inherit anything from the master tables. You have to explicitly copy the master to the lower levels.
