Branching with Appropriate Menu (Table of Contents)

Hello. If a class is branch into two primary directions (one being initial, one a refresher) is there a way to only show the menu presenting the direction selected? The reason: this training is required as both initial and annually. Two different course codes can not be used. Instead of using the same class each year, the goal is to create a review for the annual requirement. It will be included within the same class branched from a selection after the title page. Im trying to hide the menu of the other "class" based on the beginning selection. Thank you.
