In the example below the job share will be for teachers Jenny Smith and Andrew Brown.
Assign one teacher to the classes (Jenny Smith) and make a mental note that that is a shared class (i.e. Andrew Brown also teaches the class).
Any students you wish to be placed in/out of that class would need to have Student-Teacher Pairings/Separations in the survey to that teacher (Jenny Smith).
When classes are created you will just need to remember that Jenny Smith's class is a job share with Andrew Brown.
