Please add the option to filter the in-game lineup availability by "Obtained" as well as the current "Unobtained". This would enable "Which do I pick...?" questions to look better than this screenshot, or better than 5-7 separate screenshots all trying to say what this quickly cobbled one does.

i also dont think they have the option to further filter by type of hero like legendary, epic, rare, common..... which would also be very nice. for both unobtained and obtained if i just wanted to see a specific group.
