Currently, when creating a Data Template from an Element on the Page, during the creation process, there is no way to determine the DataType that the Template will belong to.

This can prove difficult in determining which DataTemplates can be applied to which Elements.

Repro Steps:

1) Create a Studio Project featuring a MainPage.xaml
2) Introduce a ListBox Element to the Page
3) Right-click on the ListBox, and from its Context Menu, navigate to Templates-->ListBoxItem-->Create Template.

Observe how during the Template Creation and Saving process, no indication is given as to which DataType this Template will be assigned.

4) Navigate to the Resources Panel, identify the DataTemplate created in Step 3), and select it.

5) With the DataTemplate selected, navigate to its Properties Panel.

Observe how there is a blue outline around the 'Data Type' Property, but that the field itself is blank (this is a bug, and its in fact a 'String' DataType)

Expected Results: When creating a Data Template from an Element, during the saving process, the user is either informed in a read-only format what the DataType will be
and/or
The user is allowed to select the DataType to create from a DataType dropdown menu, including being able to set 'No Specific DataType', to make it a universal DataType, or some variety of choice (perhaps the user can for example, only choose between the pre-assigned DataType and 'Universal', but not go out of their way to select an obviously incompatible DataType for the Element they're dealing with)
