[FEATURE REQUEST] Ability to add multiple entity ids to services.

[maxi1134]

First of all, I wanna say thanks for this card! It has been wonderful.

I am now trying to create a template media_player that would basically control the media_players in the room in which I am.

I tried using the following with no success: [see code]

Would it be possible to try and implement this possibility? It would be much appreciated!
