1Password picking the wrong item to fill on iOS

Let's say I have two logins for a website, say for "google.com", one for my account and one for my wife's account (we'll call her Pam). These look like this in 1Password (for item name, user and pass):

Google
mailto:robaccount@gmail.com
asdkf2!!VS2aaasd

Google - Pam
mailto:pamaccount@gmail.com
asd@fdD@@22!!D

When I'm on my Mac, the one that's first up to submit is the one labeled just "Google" because it's alphabetically before "Google - Pam". This is how it should function ideally, and I can manipulate the item name to have whichever I want first.

However, when I'm on iOS, it doesn't look at that in all cases, but rather just the username to decide which to display in certain cases on iOS. When it goes to fill in the password, it will only display the username that's alphabetically first as my choice, in this case "mailto:pamaccount@gmail.com". This is frustrating because I rarely log into it, so I'm having to archive that password and pull it out when I need it. I can't modify the username like I can the item title for obvious reasons.

Is this the current expected functionality? Is there a way for 1Password to always use the one that is alphabetically first all the time for all passwords it's trying to enter data into?
