Desktop browser background (minor question, not really an issue)

Hi everyone!

Question:
Do you know if there is any possibility to manually choose wich Brave unsponsored backgrounds appear in a new window/tab and in the slideshow?

Description:
I would like to be able to customize this feature but I cannot find any way to do it (or should I download every Brave image I like and manually add them?).

I also noticed that the “default” background, the one that greets me when opening Brave, can change by itself (it already happened twice for me) but I don’t know how it happened and right now I am stuck with a pic I don’t really enjoy.

If it is impossible to change that as of right now, do you know if there is any plan to add this feature in the future?

Steps to Reproduce.
1.Enable the Brave backgrounds option and disable the sponsored images.
2.Quit Brave browser.
3.Launch it again.

Result:
You should have the same “default” background every time you relaunch the browser and no possibility to customize the default image nor the native Brave slideshow.

Operating System and Brave Version:

Version 1.75.180 Chromium: 133.0.6943.126 (Official Build) (64-bits)

Thanks for your time!
