Suggestion to allow customisation of savegame directory

I wish to suggest Mojang Minecraft to allow changing of the saved game directory. As you may know, Android now forbid amendments to the Data folder. I have some saved games that I copied out from the data directory during phone factory reset. But I am unable to paste them back to the data folder of MinecraftWorlds. I hope Minecraft can better manage this problem by allowing players to change the saved game directory, so that we can access saved games from other folders. As a player, we have been playing Minecraft for more than a year now and had spent hundreds of hours building the Minecraft World we created. If because of the android restrictions, we lose the Minecraft worlds, it will be such a pity and I guess alot of players will lose interest in the game. I hope for your kind consideration. Thank you.
