Longtime 1Password user here, but I guess many advanced functions I'm still not familiar with. For example, I'm trying to save a login which has a dropdown option for what is the start page once logged in. I've chosen the dropdown and manually saved the login. In the past, I would just delete my old login and create a new one as 1Password intelligently detects and saves those form fields. Custom form fields took me years to figure out. I'm still not sure how to replicate that behavior.
But this old website login has a lot of fields, and I'm wondering if I could just add the dropdown detection item into my old login. I see on the new one an item "SAVED ON US.XYZ.COM", then Go to, then "https://etc".
Hopefully this makes sense. I tried searching the forums to no avail. Thank you.
