Cross-platform data

I mostly play Generation Zero on the Xbox One, but recently I got a PlayStation 5. I was gonna play it but I thought of a great idea. Why don’t you make it where people can sign their account’s in to the game on console. So that if they go over to a different console they can transfer there game data to that one so they don’t lose any progress with there current character. Because I would love to see if the graphics on Generation Zero are better on PlayStation 5. To put it simply better, make it where people can sign there Generation Zero website account into the game so they can save there game and character data.
