Revit R2 Update - View Reference Search Missing

The recent Revit R2 update gave us the ability to quickly find the content you need by way of a new search feature in the Type Selector or in drop-down lists. It is also available when using the 'Reference other view' feature for callouts, sections & details. To use it you can click the Type Selector or a value field in the properties palette and enter keywords to search.

Interestingly though, this feature is not available when using the 'View Reference' tool. Another example of an unfinished tool? Fingers crossed its due for completion in coming updates!
