Question about directory and tasks

### Is it possible to have different instance of taskbook by not using in global.?
Thank to every one, I don't know if my question is clear :(

The issue names no file, test, or entry point. First clarify whether separate non-global Taskbook instances are expected and define how they should be invoked or configured; then locate the relevant CLI behavior. Done means the expected behavior is specified and covered by an appropriate test.
