How do I copy my one product design to all my other products?

[Greggy55]

Hello everyone! 

So I have setup my store and I have multiple products. 

I want to work on my product pages a bit more in the most time effective way as possible. 

So for example if I add certain sections to my one product page, how could I then copy all these additions to my other products? 

Instead of adding each section manually to each of my products. I want to just get one product page done nicely and then copy my additional work to all my other product pages? 

Thank you for any help!

@Greggy55 - go to customize settings , choose default product page and add section in that.  Any section you add from customize settings will show up on all the products
