UI for selecting multiple tables when create view is selected

As a data virtualization user when user is creating a new view, they should be allowed to select multiple tables. The current UI already allows the user to do this, however based on the feedback this is not yet intuitive?

BTW, the implemented UI and mock screens (radio buttons vs check boxes) used in usability study are different. So this Jira is to further enhance the currently implemented screens rather than coming up with a new design.
