Time Tracker like t-sheets not tied only to time working in Design Files.

I'd like a t-sheets like capacity to track time and clock in and out by project that is not tied to working in Design Files proper. A lot of my work is done in a separate CAD program, involves communication, meetings and research; all of these are billable. None of these are directly tied to DF but I do all of my invoicing and product management in DF. This would help me track how much overall time is being spent on each project. Date ranges and custom reports would be great.
