If you have an existing package in one market and would like to have the same package in another market, without building it again, you can copy it from one market, and add it to another.
To do so;
- In the Partner Center >Navigate to Marketplace >Packages
- Select a package >Click the 3 dots beside the package >Copy.
- From here, you can select which market to add to > hit 'save and publish'.
- You can then navigate to the top of the packages page, and switch to the other market.
