I want my employees to track misc time spent on clients (communications, etc.) without having to have a perpetual project for every client to track that time. In those cases, my team is instructed that every time entry has to have a project. If it doesn't have to project, then it has to have a note. I don't want to require projects for all time entries because sometimes we have time not specific to a project. And I don't want to require Notes for every time entry because if something is tracked to a project, it doesn't necessarily need a note.
