Report Visibility permissions looking at all a user's roles

We have a single landing page report for a large number of users in our Apptio. This landing page includes links to a range of different reports - some of which are available to all users with access to the system, but others which are restricted to a specific role. We use role-based visibility of the links at current to limit access to the restricted reports, so users only see the reports they are able to access.

There are a significant number of users who fall across multiple categories - for instance, all users might get report A, but only Service Owners get report B, and Operations Leads get report C. But there are users who are considered both a Service Owner and an Operations Lead, and so they need to be able to see reports A, B and C.

We would like it so the permission settings look at more than just the 'currently active' role. This is how some other permission settings work in the system, to my knowledge, in that if any of your roles has the permission to do something you're able to, so I'm confused as to why this permission only looks at the currently active role. 

Given we have over half a dozen different roles actively used, creating and managing specific new roles for every possible combination of those is highly impractical, and expecting users to shift their own role whenever they need to access a different report is a poor experience. If we were able to restrict component visibility based on all of a user's roles, it would make for a far better user experience for all concerned.
