You can share content to more than one Facebook page using the Real Estate Voice Plugin.

For example, you may have a Facebook page for your agency, and a seperate page for your personal agent brand.

When connecting to Facebook, select all of the pages you will want to share content on. You get that option when you give permission to Facebook to post on your behalf:

If you don't see the pages you want to share to, it means that the login you used to validate with Facebook does not have permissions to the page. You will need to get added as an admin from the person that owns the page or validate with a Facebook account that does have access to the pages.

NOTE that if you turn automation on - content will be automatically shared to all facebook pages you have enabled.
