Yes, this is easy to do. Go to the View menu and select Choose Popup Display Versions. This will open a dialog in which you can select the versions you want to appear in the hypertext Scripture popups. You can select one set to appear when you simply hover over a Scripture link, and another to appear when you hold down shift while hovering. This is effective for all Scripture popups, both in the Analysis window and in, for instance, the Greek and Hebrew lexicons, dictionaries, and so forth.
