Hi Tim,
I agree this isn't great and I would also like to see it improved.
We are actually working on bulk actions and have rolled out a BETA that people are welcome to message the Activations team to try.
Although this BETA does not include bulk delete from the archived section, it's something I would really like to see and I've passed your concern to the team in charge of that feature. While it's not something that's being worked on right now, it is something they're considering for the next round of changes for bulk actions.
If/when I have any update on this topic I'll update you here.
Thanks.
