Project profitability

Project profitability

Hi, 

Is it possible to follow-up project profitability in Zoho Projects (or Books, but in this case it might be good to have a link between projects in Books and projects in Projects) ? 
I saw that I can set a budget and register expenses in Zoho Projects but what would be really good is being able todefine a cost by employee so every time he logged an hour on a project, it increases the expenses (and increases the revenue if the project is billed based on employee hours). 

Is there a way to achieve that ? 

Best regards, 

Perrine
