Support for Additional Fields

Good afternoon,

I am reaching out in search of support for adding additional fields to a password entry in 1Password that will auto-fill.

Certain websites which have additional login fields do not seem to always be detected during setup. If you try to add them manually later, they either fail to autofill or don't prompt to save.

For example, the "Employee Login" at PayCom requires three fields:

1. Username
2. Password
3. Last 4 of social

https://www.paycomonline.net/v4/ee/web.php/app/login

Username and Password properly auto-fills, but I am unable to save or auto-fill the social.

Is there a way to resolve this on my end? Is it an issue with recognition for this particular website?

Thanks!
