Restore and just overwrite old stuff

I just want easy way, use backup ZIP file and push 2 buttons.

Nearly everything is about Migrate or Restore the hard way, delete everything and create new WP and database, write passwords….and then run Restore (really messy)
Why nearly nothing about Restore the easy way, just use backup ZIP file and push 2 buttons and overwrite old stuff ?!?
With Softaculous “Push to live” I think with staging it overwrite all old stuff, easy way.

I have several backup ZIP files that is from regularly backup with Duplicator Pro.
Duplicator Pro is good, I just want to Restore easy way.

(only have Duplicator ZIP file, no staging file this time)
