Absolutely! We've expanded our Post to Facebook feature to now allow you to post on any Facebook page that you are an admin of. Follow the steps as normal and you'll be given an option to choose which page you'd like to post on.
There is also another way of accomplishing this, by copying that link manually; seen below.
Click Publish Online and you will be given a link to copy:
You can then use this link to post to any page on facebook that you would like. When you copy in the link, facebook will automatically generate a post with a thumbnail and title based on the marketing piece.
If you would like to test this before posting publicly on facebook, you can restrict who can view the post to Only Me, then post to make sure it looks okay; seen below.
