If your products have a lot of similar attributes, chances are you'll find our "copy" feature extremely useful.
Copying a product simply means that it'll create an exact copy of all the attributes, so that you don't have to re-enter them in.
To copy a product, click on the Actions dropdown and select "Copy".
You'll be taken to the "Edit" view, where you can change any of the attributes.
For example, you'll want to change the product title, since it is now named "Copy of [title of copied product]".
Please note: When you copy a product, it will also copy the sales channels that it is currently listed on. When you Publish your copied product this is where it will be listed. Coming soon is the ability to select what sales channels you want to copy the product to instead of assuming it's the one's it's currently listed on.
If you want to add/remove the product to/from sales channels, you may find these help guides useful:
