Feature request: a separate vault with different access methods within a 1password account.

Hello, I got another question.
Can I perform operations like changing my account type, changing my master password, regenerating my secret key, saving my emergency kit, changing my billing method, etc in the mobile or desktop app instead of possibly less secure web browser?
I believe 1password7 had all this features in apps but it seems to be gone in 1password8.
Any help would be greatly appreciated!
Thank you in advance!
