Ender Dragon Specific Portals.

In 1.6 Bedrock Edition, the ability for the Ender Dragon to move between dimensions was removed due to the Ender Dragon ending up in the overworld via the end altar portal being opened before the dragon was killed. I would like to propose post Ender-Dragon portals that would only allow the Ender Dragon to go through them(could only activate through player means). This would mean that the Ender Dragon can still can through dimensions but would not be able to if the player had not intended for it to happen. This would improve room for creativity and such, which Minecraft is all about. After all, The Dragon is an inter dimensional beast, and dragon’s are usually seen as magical creatures. This it should have the ability to move between dimensions.
