Request for Folder-wise Filter Option in Expense Book

I need your kind guidance regarding the Expense Book.

In the Overview screen, there are two sections: Fixed Expense and Variable Expense. It would be very helpful if there is an option to filter folders by selecting only the required ones.

For example, all my purchases are not only for me or my family. Sometimes I spend money for my friends, relatives, or others. These expenses usually come under variable expense.

If there is a folder-wise filter option, I can select only the folders I need. Then I can easily see my own expenses or selected expenses for a day, week, month, or year.

I am not sure if this option is already available. If it is, please guide me. If not, kindly consider adding this feature.
