Add option to open URL in Incognito browser window

I see this is an old request. I would like to update it with a similar request:

I have some regularly visited web pages that I need to open ONLY in a private (Safari) window. As things stand, this requires me to 1) remember which pages have that need; 2) manually open a private window; and 3) make sure 1Password opens the page in that window. It would be much better if I could configure the URL in 1Password to do those things for me.

While we're at it:

 There are also some sites that only work in a browser other than the one I otherwise always use (Safari). I would like to configure those URLs so they automatically open in the required browser.

I think I'm far from alone in wanting more flexibility in configuring how a URL is opened.
