Disabling specific items from being suggested by Safari extension?

I'll add my voice to the "please add" group. There are cases where I have passwords to sites in 1P that I need to keep, but don't want to be prompted about (supporting parents, kids, admin-accounts, etc.) and that was a nice feature to be able to tell 1P to not prompt me for stuff. Yes, it's a corner case vs. the millions of users that don't use it. But one of the nice things about 1P is it had cool features for the power user. Please don't "dumb it down" too much.
