How to merge already created lessons in TimeTables Online

In case that you have imported lessons from other systems, or you have changed already created lessons in a way that it would be possible to merge them into one record (same teacher+subject+class/group+classrooms+length), it is not necessary to do it separately for each such lesson, but you can use global function "Merge same lessons".

Use menu "Specification - Lessons". There you can see all lessons in your timetable. You can either select all lesson at once - by using "Ctrl+A" - or use filter and select just a group of lessons. Then click on "Change" - "Merge same lessons". Confirm this change for selected lessons.

Note
- this function will be visible only there are such lessons which could be merged among selected lessons
- this function change only those lessons, which could be merged. Other selected lessons remains unchanged.
