How to add new custom categories for work item states in azure devops?

I want to create new categories for work item states in azure devops . Also is that possible to create a new workflow and map that new categories to the new workflow. Thus creating an entirely new workflow and categories in Azure Devops?

If you are referring to add custom categories as shown below, I am afraid this is currently not supported in azure devops . We can only add custom states but not custom categories .
