Feature request: Mark password as suspect

After Heartbleed, I have it on my todo list to update a bunch of my passwords. But the fact is, I have too many logins in my database for that to ever be practical. It would take me hours and hours.

Instead, I'd like to be able to select a bunch of passwords in my 1Password database, and flag them as "Suspect". Then, whenever 1Password tries to fill in a website with such a password, it will prompt me with a dialog saying, "This password has been marked as suspect. Please change the password at your earliest opportunity."

That would force me to update all of my important passwords on as "as-used" basis.
