AdBreak with Ads enabled gives only one screensaver

Hi,
Just jailbreak a Kindle Paperwhite (11th Generation) ... With AdBreak and success 😄 Very grateful!!!!
But it seems I do have now only one "screensaver" (plenty of letters all the way around) which is nice, but boring after a few days.

Is there a way to change that behavior, set my own, etc?....  Or not yet?... Or never?

Thanks
