It's possible to have a different background per user in the login screen?

As the title says, I want to know if this is possible to set, like in Windows 10 and 11 where you can customize the background for each user in the login screen, so when you select from “User 1” to “User 2” the background fades in to the selected background user’s.

At the moment this is not possible.

Thanks for your answer, I hope in the future that feature gets implemented.
