Tips from a foreign language teacher

As a person with many classes in a year (I currently have about 7-8 planbooks), it would be great if the customizable templates could be saved. I have to edit them in every single planbook, every single time. That is, whenever I create a planbook, I choose a random one and then edit it individually. It would be lovely to have my own templates saved to use every time I need to open a new class.
