force redears to pin specific link

I’m using wordpress and I split each post into 3 pages (post pagination using this shortcode <!--nextpage-->)

Domain. com/post-example/

Domain. com/post-example/2

Domain. com/post-example/3

Etc

I get many re-pins in my website but most of them from the last page of the post Domain. com/post-example/3

Is there any way to force Pinterest to save first page link instead of the last page link

I know there some plugin with these functions but the problem is the most visitors use Pinterest browser button in mobiles

Can't you just write on the top of that page something like:
"Page 3 of 3. Go HERE to read from Page 1"?
