Insight report eloqua filter - Switch to Exclude

Hi,

I want to know if this is achievable in Eloqua insight report or not?

Use case: I have a list of contacts for external activities to upload and few of the contacts got incorrectly updated as 'Attended'. So, we have a way to exclude such records from the report by uploading another external activity as 'Error'. Now contact 'A' has correct External activity as 'Registered' and incorrect activity as 'Attended' and another External activity as 'Error'. Is there a way I can exclude such incorrect records totally from single report, vene if they have correct external activity:

Filter: Do not include {{ external activity = Attended AND external activity = Error} OR {external activity = Registered AND external activity = Error}}
