Management Reporting - remove the 300 rows on grids limit

Margot

It would be great to have the limit of 300 rows on grids removed in the Management Reporting area. Management Reporting may be used to have these fast variance & variance % comparisons but the 300 rows limit makes it unusable in many cases. The 300 rows limit is also applied when exporting to csv - it would be a good first step to remove the limit from there.
