# How to add custom Work Categories to a Phase or Subphase on Project Schedule Modal?

Custom work categories allow you to tailor the project management process to the specific needs of your project.

Similar to **Phases** and **Subphases**, **Custom Work Categories** provide flexibility in organizing project tasks. Instead of using standard **Work Categories**, a **Custom Work Category** can be created and tailored specifically to the needs of the project. **Admins, Work Planners, and Budget Managers at all levels** will have the ability to create **Custom Work Categories** as needed.

1.  Click the three-dot on the Phase where the Work Category needs to be added. Select **Add Schedule Item** > **Add Work Category**.

    > **Warning:** Work Categories can only be added to Phases when the Phase Time Tracking setting is configured to "Track Time By Work Category."

    > **Info:** Once the custom Work Category is created, you won't be able to delete it completely from the list, but you can rename it.
    
3.  To create a new Custom Work Category, enter a name, indicate if it is billable, specify whether an additional description is required, and click **Create**.
