Different landing-page depending on language

I’ve installed the Polylang-plugin and it has made a problem I was expecting to be big, surprisingly small! However, I only have a part of my website translated (support-area) and I therefore want visitors to land on the support-page when they select German or English.
When they select Danish, they have to land on the front page.

When I try to set this up, it forgets the landing-pages for the “support”-languages as soon as I set the front page for the main language.

Is there any way to work with different landing-pages depending on the language?
