On Facebook it is possible with Swat.io to target a preferred or even a restricted audience in each individual post. This function can be found at the bottom of the post creator in Publisher:
Additional details can be added for this function, which is aimed to target a preferred group. The posts can be narrowed down by age, education level or even geographically. Templates of the selection can also be saved, in order to be quickly selected for further posts.
To achieve exactly the opposite with a Facebook post, in example to exclude a certain group, you can use the "Restrictions" function. This offers similar selection options and excludes a certain audience from seeing the post. Templates can be saved for that as well.
