In the page builder version 3 in Goodlayers theme and start from Infinite theme, it’s support Sync Template option. You can follow my guidance to use it in your site.
First, we will need save something in sync template, it can be a wrapper/column or whole template but it must include in a wrapper.
Then go to the target page and load the sync template and save the page.
Now, you can try change something to get your result, you will see the sync wrapper as my screenshot to help you know it’s sync template.
