Allow naming of Connected Data items

When connecting Data from Builder CMS Data Models (using Connect Data in the Data tab in the Visual Editor), the names are automatically generated using the name of the Data Model and then appending an incrementing digit (i.e. Pricing, Pricing 1, Pricing 2...).

It would make life so much easier to keep track of what data model entry is selected for each of these if the name of the Data Item could be edited, so they could be bespoke names.
