Semester long classes AND A/B in the same Planbook

Our school is on a semester schedule with most classes being held every day for the semester, but we also have specific blocks were the classes are on A/B schedule. I would love to be able to set up these classes in the same Planbook so I can look at all of my classes for the entire year in the same book instead of having to have two-- one for my semester classes and one for my A/B classes.
