How to create the sub-role?

Example: Consider the position of Forklift Operator in your factory. Each forklift, equipped with a tablet, may have different weight capacities, such as 3 tons, 5 tons, or 12 tons. To manage this effectively, you would create a work role called "Forklift Operator." Under this main role, you can assign sub-roles based on capacity, like "Forklift 3 Ton," "Forklift 5 Ton," and "Forklift 12 Ton." This organization allows for clear role assignments based on the specific capabilities of each forklift.
