Players, in survival, to able to create their own trial spawner challenges.

The trial chambers host a new, challenging and exciting challenge for Minecraft players, focused around the new Trial Spawner technology. However, that new challenge is currently specific to the trial chamber, which is brilliant in making it unique, but misses out one of the biggest aspects of Minecraft - creativity! I believe trial spawners should be able to be moved around, so that players can create their own challenges by, in vanilla survival mode, building their own structures which host trial spawners. Players could then set the spawner to spawn a specific type of mob based on the blocks they put around the spawner. This would allow players to create their own unique, custom trial challenges for them to take on! Now, of course, it’s also important that the current trial chambers are preserved. We don’t want this new feature to ruin the current experience, so it’s important players don’t just go around trial chambers smashing the spawners up and taking them with them before the challenges begin. So, maybe there could be an item you get from the trial vault which allows you to obtain the spawners - a pickaxe enchantment maybe? This would mean players would have to face the trials in order to make their own. Now, this doesn’t have to be limited to the trial SPAWNER. Maybe trial vaults could be carried over too, and the loot table could be determined by players putting items in there themselves, like a chest, to be only spit out when a challenge is complete.
