QOL - Can we please get an arrow for full clear challenges?

I've been trying to get the twinned challenge in Prophecy.



And then, just when I thought the hardest part was done, the last two maps have been absolutely, incredibly, unbelievably, inexplicably, and frustratingly annoying, e.g.:



I have been back and forth through this and nothing. I also tried a tier 8 twinned with a friend to help, and still none of us could find the last pack.

GGG, Please give us an arrow (like in some Tora missions) for <X remaining, where X depends on how generous you are feeling right now.

If you do, I'll buy a supporter pack, I promise!

Ew terrace.
