You can link standalone categories of an event to your tour in order to include them to the tour standing.
To do so open your tour in EventMaker and navigate to the "Categories"-Tab. Once you have selected the related tour-category you can start the process by clicking the "Link category" button.
The wizard will guide you through the process and show you existing unlinked categories that can be included. Pick the one that you want to include and save your changes.
The system will include the category to your tour standing and treat it as part of your tour.
