Labor costs allocation by percentage of time spent in Oracle PPM cloud

Summary

Looking for alternatives to capture labor costs and perform an allocation between different projects by percentage of time spent

Hello PPM experts:

Our non-profit project centric organization is currently relying on time card entries to capture labor costs by projects, but we want move away from this approach. Mainly because everybody is required to enter a time card, including Admin and other non-project related employees (and managers). Additionally, time entries are based on hours worked (not percentage of time spent on an specific project/task). 

Our Research Funding team is looking for an alternative to allocate labor costs for external funded projects by percentage of time spent. They are even looking at a third party Grants Management system to accomplish this and then interface it back to Oracle. HR is on board with discontinuing Time Card entries in Oracle as long as employees report exceptions (time off, vacations, etc.).
