Refined scope for burndown report

Hi, I currently have a rolling story point burndown report (timeline view) which we use to track progress and forecast completion. At the moment the filters to help refine the scope includes ‘Issue Type’, ‘Label’, ‘Fix Version’, along with a number of other options.
Obviously any selection here applies to the entire data set.

I’d like to be able to filter the data by combining some of the existing filters using OR rather than AND, which will (I believe) need a calculated measure…

For Example:
‘Issue Type’ = Task
OR
(‘Issue Type’ = Bug AND (‘Label’ = “Ignore” OR “NotTriaged”))

Any assistance would be gratefully received!!
