mifos -- splitting savings into member and donor(sponsor) for a single saving stream

Hello it would be good to split accounts(saving stream) within an individual's saving account such that u can separate saving money streams from for example ( if parents were contributing for their child) a father , mother and the child OR if an individual is receiving topup contributions from an association which are dependent on themselves making a saving( the association will give you a saving only if u also contribute and it is necessary to show  what each party has contributed)
