In the Planner Settings and Layouts menu, please navigate to the Daily section and click on it.
You will see 2 pages for which you can choose layouts.
Click on the first page and select the layout that works best for you, then repeat for the second one. You can choose different layouts or the same layout, which will add 2x times more daily pages.
If you need even more daily pages - you can try Daily Digital Planner, which has 4 Daily Pages to configure.
