This has been thrown a round before and I think some changes were made?
Results by blind levels were not grouped because of (6 Max) tables had their own blinds?
Anyway, In Hands Reports when you sort by Blinds, you can't get all the common blinds grouped together because (6 Max) tables had their own blind structure at the bottom of the report.
I think they should be grouped by Blind levels regardless of table size, and allow quick filters to remove table size. At least this way you have the ability of grouping the blinds together.
