Filing of ITR 4

Can somebody please help me to file ITR 4? In Goa, system of Community of property is prevalent, as per which  income of the assessee (except salary income) is shared in equal proportion by the spouse. I have downloaded ITR 4 excel utility from www.incometaxindiaeflining.gov.in site. But it does not show the provision where I can show half income of spouse. Please help.
