User Friendly Filtering in Email Performance report

It would be great if in the following possibility would be added in the 'Email performance report' in 'Marketo Analytics':

When filtering in the setup area on a certain word all emails show up with that specific word in the title. Currently you need to select them one by one to ensure these specific emails are taken into account in the report. It would be great if you can select all these emails add once. Currently when you click default you still select ALL emails in the environment.
