Work with several Github repositories under one project

In my team we have several related Github repositories and we want to use Github project boards functionality. As I see, each specific project should be linked with some specific Github repository. But what if I want to have one Project for several repositories? Is there any possibility to set it up this way?

Looks like if your team is working from an organisation, you can set up a Project on it:
