I would like to have an option to exclude certain entries when you're reporting (but before exporting to pdf etc). Something like an option to 'edit' that brings up tick boxes next to entries so they can be excluded and when the exclusions are made it returns to the original report screen without these entries. I think having the tick boxes in there permanently would affect copy/pasting of the report. Would this be possible whilst still maintaining the current format?

this might not be very clear so I'll try to explain a bit better.
e.g. reports > configure report > current report screen > edit/exclude button > brings up tick boxes > apply button > returns to report screen in the current style but now certain entries are excluded.
