Make menu flag language NOT being displayed (with 2 languages)

Hi there,
Love the plug-in but have a weird UI question I wonder if there’s a solution for. I have a website that’s in 2 languages, but in order to show users that the website is in 2 languages, I was wondering if the language switcher could display the language the website is currently NOT in i.e. if the website is currently in language A, have the button default to language B. At the moment, if a website is displayed in English, the default flag is English and to see the other languages you have to click the drop down. My website has 2 languages and was wondering if there is a way to have the language shortcode / menu item display the flag for the language that’s currently not being displayed so that users are able to see the other option available to them.

Hope that makes sense
thanks
