Duplicate screen or create additional link to screen

I have several screens that are linked from a menu page that is made from graphic images
Some of the pages are quite complex data entry screens and I would lie to be able to

  1. copy them to make slight changes for different scenarios or
  2. to be able to link to them from another page or from a tab
    So the basic questions - are the screens actually stored somewhere so that they can be copied and/or is a link to them stored somewhere that I can access and use

As far as I aware, you can only copy tabs.

“Link to screen” screens are not saved anywhere to be copied by devs, but I hope it will become a thing in the future.
