How to set only one approval delegation for all approvals

Summary:

In Approvals and Delegations page i am able to see multiple values under category. If i want to set approval delegation for absence i have to select category as 'GlobalAbsence Approval. If I want to set approval delegation for workforce structures i have to select Workforce Structures (e.g. Job, Position) category like this we have to select category as per requirement.
