Workflow Delegations/Substitutions

I am using Universal Worklist in Self Service and I have a question regarding delegations/substitions.

If a Manager delegates his SAP responsibilities to another Manager on the same level or higher does delegation rules apply to all the listed tasks below? Or do the tasks have to be assigned individually?

Tasks

a.MSS requests

b.Adobe form completion

c.E-Recruitment requests

d.PDR/Appraisal requests

Thanks
