Facebook Boost Post filter criteria

Does anybody know when boosting a post if there is a way to exclude people who already like your Facebook page?

I see Exclude people who match box, is that where I add this information and if so what would I put or is it located somewhere else?

I am trying to stay away from advertising a boosted post to someone who already likes my page.

Thanks!

Create an ad in the Ads Manager instead of boosting post.
Use post ID as an ad, and choose connections you need as on the screenshot above.

Thank you and that worked out. It took a while to go that way but I got it done, thanks again!
