Possible to add some static data to TreeView within Glade?

Question

I have seen the existing question but I am not sure if adding actual data in Glade is possible or not.

I have created a TreeView and added two columns. I created a TreeStore and set it to the TreeView. And how can I add some static data like the following within Glade?

Data are stored in a store, such as GtkListStore, not in the view. To add them, click the store the widget on the glade.

At the bottom right corner of the image below, there are options to Add and remove rows.

Moreover, to associate the view with the store, the Text option in the cell renderer must be set to the corresponding store column.
