Collection Editor Dialog Box (WPF)
The Collection Editor dialog box in the WPF Designer for Visual Studio is used to add items to and remove items from a collection property in the Properties window. The Collection Editor is available for any property in the Properties windows that has an ellipsis button. For example, when you add items to the RowDefinitions property of a Grid control through the Properties window, you use the Collection Editor.

If so, you can open a nested version of the Collection Editor for that collection.
