As a service company that has multiple stages to a project it would be great to have the ability to make a specific job task inactive to prevent any time being posted to that task once it has been completed.

For a simple example a project has three task lines:

Line 1.0 Phase 1

Line 2.0 Phase 2

Line 3.0 Phase 3

Phase 1 of the project has been completed. Task line 1.0 is made inactive

Phase 2 Starts, task line 2.0 is made active

Phase 3 has not started yet, task line 3.0 is inactive.
