How to make Question digest page into homepage?

Hi There, I am using Q&A plugin. Looks good for now. How can I make main page of the Q&A section into homepage? So what now is /questions/ should be home.

I was hopeful that i can select that in WP settings, under make homepage static page, but there was no option to select Q&A main page there. I could do some 301 redirect (home -> /questions/), but that may not be the best solution. Can you please advise me what could be the best way to do it?

Thanks, Regards
