Zoho Invoice, sub category option to track Expences in specific projects within the organisation ?

My question is, how can I add specific stand alone projects under subscribed organisations, I am in the construction industry and I need to separated Expences for each project so that I can track and analys each project with its own income and expenditure, also I need to also have some kind of drop down menu to select the account certain Expences have been paid from. Is all this possible or not? And if it is x how and what do I do.
You're assistance would be greatly appreciate.

Thx

Ned
