While Im no moderator, its been generally accepted that you can have a save on the correct spawn due to the extreme RNG required to get the correct spawn in the first place. Typically, you are not allowed to leave the plane except to check the spawn, and since you are in creative mode, there shouldnt be much of an issue to create a save point.

There are some save files floating around out there, but its probably easier if you just load in a bunch of times and find the one you want. That way you know its set to the current patch! Hope this helps!
