It sounds like you need a more flexible meal planner that allows for greater creativity and customization. Assigning meals by days or weeks is a great start, but it would be even better to have a hybrid system that takes into account not only the days and weeks, but also times and phases. Additionally, having the ability to adjust caloric intake percentage and having the meals populate based on these inputs would be a huge asset. With these features, you'll be able to schedule your clients with eating plans that vary 2-3 days based on their workout and calorie intake, all while allowing for more variety and customization in their meals.
