Facebook feed with only certain Hashtag

I am looking for a free or cheap plug in that will post 3 facebook accounts feeds. But I can only post 1 certain hashtag from the feeds. does anyone know a plug-in that will do it automatically so I can’t have to embed every time.

It can only be hashtag from these 3 accounts. This hashtag I am using is used be 100 plus accounts. Pro-fisherman.

thanks,
