developing AAC controls: how to filter on self-conflicting roles

I'm sure there is a fix for this and you've done it.

in Access Control filters, I need the logic as with usual Reporting syntax to state; "exclude results where role name = conflicting role name".

simple? Access conditions.role name condition does not allow 'does not equal' ..but even then, doesn't have the option 'conflicting role name' to select.

we all have SoD entries like this due to our complex custom roles and having the aftermarket 'Conflicts within a single role' button to remove them is a manual step we can avoid surely.
