Export maps from PS4

On the PS4 all save games (for all games) are encrypted specifically for the user that played.

The reasons for this I've seen are all related with game progress and trophies.

If you copy a save game from one player to another (I've tried with a USB) you will see an error indicating the save game belongs to another user.

So if you want to share a map you created with someone that is currently impossible.

What I would like is an option to save a single map in such a format that it can be loaded into a different account with effectively the same status as having played a map in creative mode (i.e. no trophies and such).

It's fine if this requires me to copy it to and from a USB stick.
