Merging lessons in the lists in Timetables online

On picture below you can see the list of lessons for the class. You can observe:

1. GREEN - two single and one double lessons from Biology. They are with the same teacher and class but different in classrooms settings. Therefore they are displayed as two separate rows.

2. RED - One double and four single lessons for English language. They are with the same teacher and class also, but this time with the same classrooms settings too. Therefore they are displayed as one row with merged count/length settings.
