sub account

Hi, until recently I had a smartphone with windows to the past are now Android. to manage my accounts and my expenses will organize the first using casg organizzer program, now working with Financisto. It is a very good program but lacks the ability to manage sub-accounts. for example I have a master account is called " ammortamenti", and many sub-types with different depreciation. The sum of the sub is obviously equal to the depreciation account balance. Today with financisto I do a similar thing with the filter and managing the sub as Project;. but in this way I have all the movements and not the balance. So for each project, then I have to make a difference for algebraic understanding of the balance. You can implement the program in order to manage the sub? Thanks
