How to turn perspective zoom off in iPhone shortcuts in ,y iPhone 12 Pro Max with iOS 14?

I would like to set a shortcut to change the wallpaper automatically, all the things are good, except that I cannot turn the perspective zoom off in the shortcut, which my photos are already fitted in screen ratio.

Please help or add it in the future update.

Moreover, please also add the time internal setting in automation, for example:

From {a specific start time/immediately after the automation is on}, execute a shortcut in {a preset interval (in mins)}, until {a specific end time/infinite}.

Thanks.
