User based access vs Role based access

Product: PowerShell Universal
Version: 3

Is there an easy way to give a single user access to a few scripts without using roles or tags?

UserA

• Script A
• Script B
• Script C

UserB

• Script A
• Script F
• Script G

UserC

• Script A
• Script B
• Script D

We also would like to give User A access to one specific page on a dashboard. Are we overcomplicating things?

We are currently using Windows auth and have some custom roles set up that are tied to AD groups.

Thanks
Michael
