In the 'Configure idea portal' you can change Terminology. There are about 30 items you can change, but there is no possibility to copy Terminology from another Idea portal. That means you have to change all items by hand. That's not efficient and it's sensitive for failures (grammer and unambiguous).
Seems easy to create a copy button: small effort, great advantage.
Thank you for the request. As described, we currently provide the ability to customize the terminology for approximately 30 items in Ideas portal, to allow you to fully brand it and make it your own. It's also possible to add multiple products to an ideas portal, so that there is a single destination for your portfolio.
We can understand the potential pain point of having to change all items across additional products. However, as this is a one time action, it appears that it is not a huge pain point as compared to other focus areas of the application (where actions are repeated). At this time, based on community feedback and the current workaround, we are unlikely to make changes in the near term. We hope you can understand.
