Copy Record Button On View Page

Good Morning,
I am trying to figure out how to use the "copy" function from the list page on the view page:

I would the option to copy the current record from the view page to add a new record ( Add Litter Mate ).

Here is the overall desire.
I run a pedigree site and user add their dogs to the site.
When they create a dog, they are taken to the view page.... I need an option on the view page to copy the current record
When a user is adding multiple dogs ( an entire litter ) it is cumbersome for them to search for the that entry in the list page ( well over 10,000 dogs in list ).

the list copy is working as desired based on what I put in the "Copy Page:onload"

I need this function on the view page as well...

any guidance or help where I can find this in the manual or an example code that I can look at would be appreciated.
