    Given a client's financial portfolio containing multiple lists of investment categories and spending areas, create a function that alphabetically organizes each group of financial planning elements to improve report readability and analysis. The function should take a nested list where each sublist represents different aspects of the client's financial plan (such as savings goals, monthly expenses, or investment vehicles) and return the same structure with each sublist sorted alphabetically.
