Link Bedrock Worlds!

Many Minecraft Bedrock players have Minecraft on a few devices and know the pain of going on a trip or long car ride and making a new world on their phone just to never be able to play on a console without a realm or paid service. So what if there was a way to link worlds to your account? The Idea: What if Mojang made a one-time pay world slot almost like a realm, but it was only on when you are on and only linked worlds to your account, not a realm. Yes yes, my idea is just a realm basically but not on 24/7. I know, "another cheap realm clone," but think about it: all this does is move the world storage from local to the cloud for one world at a time. So it's a one-time pay (I'm thinking like $10-$20) and it is a slot that you can put one world in, not three, but in the same menu I guess. Then it gives you like 5 GB of space on the cloud to use your world like a normal world. You host it, you let friends join when you are online, and yeah, just be your average world—but it's on all your devices. Isn't this what Bedrock is? Minecraft anywhere. And now, if this idea got super duper lucky and got added, then your world is anywhere too!If anyone has a suggestion or an idea to make this better or fix something, comment it and I'll add it to the idea.
