As title says. Something like “spoiler:last3episodes” would be a nice change so I won’t have to update my filter every other day.
 
That said it’s the last season anyways so RIP…

Only something like spoiler:s09e1? which will cover all episodes from 10 to 19. spoiler:s09e2? will cover 20-29 episodes.
 
But you may fill your tag filter manually with all remained episodes right now, you don’t have to wait for images with required tags.
