Can Zoho People or Project app. manage simultaneous participation in different teams/projects/more than one person to report? 

Can we plan that employee efforts utilization in hours not in days: for example the load on some task A is 2 hours a day, and 6 hours are vacant and can be used. And we plan an employee will be occupied with task A 2 hours a day during two weeks. And he will also be occupied 3 hours a day with task B during one week. So does any Zoho product allow to plan working time in hours, and avoid dividing Task A on 10 everyday Tasks each 2 hours long?
