Use 2 different email adresses depending on checkbox input?

Hello,
working on my very first homepage and making progress step by step.
At present still in coming-soon-mode, so not much to see…

Regarding the contact form, we have the following idea:
We would like to display two checkboxes (or radio buttons) to choose from, and, depending on which checkbox is active, use a corresponding email adress.

I guess I know how to include checkboxes in the form tab. I also saw that in the tab “email” there could be a 2nd email activated in the bottom, but in the documentation it says it is used only if the first email is used successfully, so this seems to be no direct solution…

So, I guess I have 2 questions:
1. is there a way to alternatively use 2 different email adresses?
2. how would I create the dependency “if checkbox1 is active, use email1; if checkbox2 is active, use email2”?

Many thanks in advance!
