In order to recover a previous used filter by name. We can use the dialog for custom report (My reports), even we can remove custom reports completely, because the user could combine recover filters and generate PDF with the same effect.
Maybe using My reports for this is not the best option, because the current way of defining filtering, ordering and columns directly in list is more intuitive than in 'My reports' (because it uses direct manipulation) and it's more agile (you have to do far less clicks). Just adding a way to save and recover the current filter would be enough. And with this we could even drop 'My reports' completely.
