Manually Add Credentials to Saved Logins

My wife & I share this Windows computer & each of us have several signons on various systems. Right now my wife is signed in using her credentials & I wanted to add a few signons in Brave (two are Google accounts) but that would require me signing my wife out of her Gmail account.

I thought about exporting my passwords, adding a the new entries to the CSV file in notepad & importing the updated file but would rather not risk scrambling the list of passwords in Brave (there are currently 63 rows in the exported password file.)
