Can we add two constraints

[moke]

    Can we add two constraints: a priority time period for a group of activities and an exclusion time period for a group of activities?
    In our school, English and math are taught in Class A and Class B based on the natural class. That is, other subjects are taught in the natural class, and when it comes to English and math, they are divided into Class A and Class B. Due to the shortage of teachers and considerations for teaching effectiveness, there is a math teacher who teaches Class A of students 5, 6, 7, and 8, and a partner teacher who teaches Class B of students 5, 6, 7, and 8. During class time, Class A of students 5 and 6 attends the Class 5 classroom, and Class B of students 5 and 6 attends the Class 6 classroom. When scheduling, the math classes of classes 5 and 6 are taught at the same time. Sometimes, this teacher would like to give priority to teaching in the 2nd and 3rd time periods, and does not want to teach in the 1st time period. Is there any good way to solve this problem? If so, please let me know. Or, as the title says, can we add two constraints to solve this problem?

Hello!

Please investigate the preferred times for (sub)activities constraints.

Is there a way to combine these classes into one activity? For example, it would be more convenient to combine the math classes of classes 5 and 6 into one activity.

You can add two students sets to an activity, or use constraint activities same starting time.
