Blacklist of media and player

Situation:
Sometimes, for various reasons, we want to restrict a video so that it is not displayed on certain players.

To achieve this, you need to create a playlist for each player that has videos that are not to be displayed on the player. where in this play list there will be no video.

Solution:
Blacklist: What if it were possible to add a media, to be able to define which players will be on the blacklist, ie where it should not be displayed.
Also, when adding a player, it is also possible to define which media should not be displayed on it.
Even if it is scheduled the constraint will overlap.

It would be a great resource, and a great evolution in the management of the media.
