Hi Robert,
By default, there is not an option to add more than one FB page, this would require editing the plugin files. You could add the widget a second time to a widget area and add a different FB page but then it would require some additional CSS to probably have it display nicely for you.
If you need assistance with any customization you could ask in the community forums here: https://studiopress.com/forums/
You could also check out the other community resources such as the Slack channel ( https://genesis.community/slack ) and Facebook group ( https://www.facebook.com/groups/genesiswp/ ).
Kind regards,
