How to setup admin roles for user in PeopleSoft?

We are on PeopleSoft HCM 9.2 PT 8.59. When we add a new admin IT user to PeopleSoft we have to setup their security with new roles. The City I work for has Active Directory accounts and non AD accounts. For IT Admins we have our AD account and we have to add about 140+ roles to that account to make them "admins". We also have to setup another non-Active Directory account so they can use that for loading ExcelToCI or opening App Designer. That account only has about 40 roles.

I'm wondering if there is a better way and why there are soooo many roles to add!? Is this just how it is and others have automated the adding/removing of admin roles to user profiles, or should I really be only adding like 1-2 roles? Curious how other organizations manage this.
