Another way to create a Data List in Impact Designer is by copying an existing Data List. This is an ideal option to use when you need a data list containing the same values as an existing list and looking to make minor changes.
Copying a data list will copy all of it's attributes except that it won't be linked to a form until you assign it.
From the Data List page, locate the data list you wish to copy and click on the Copy button beside it.
Next, enter a name for the new Data List and click on Create Copy.
You will now see the new data list in the Data List Page. If you need to, you can edit the data list.
