Only fill login on selected domains

I think this was something I sent to the team directly a couple of years ago and no joy yet. As (amongst other interest) a genealogist there is a feature I am desperate for that I constantly miss from Dashlane. The ability to set 1Password to only fill the login details on a domain. There is nothing more frustrating that having 1Password pop up in evert single search field of a genealogical website. At times I thing do I have to login then switch the extension off, but then I often jump between websites and need it's services elsewhere. 

I love so much about 1Password but this is a 100% frustration that dim's the pleasure of doing the research. Apologies if there is already a setting to do this but I have searched everywhere and haven't found it. Thanks in advance and here's hoping...
