Where do you set the default vault for new items?

I would like a way to save to my shared vault by default. My partner and I both find the current default quite annoying. I can't tell you the number of times we've said "Hey, where's the password for " "It's in 1 Password." "I don't see it." "Oh, it must be in my private vault, hold on. Ok, shared. Sorry about that, stupid default." "Thanks. Yeah."

It was amusing the first few times but it's gotten really old. I can understand why you don't want to make it the default, or even make it possible to do by accident, but could we please have a way to say "yes, I really really do want to share things by default."
