Sorting button in Select Element dialog is not intuitive for some people

When you paste a View and open its Select Element dialog the sorting button on the bottom is sorting the Alias names (screenshot).

Some people expect that this button actually sorts the elements on the left side (yellow marked in screenshot) but actually it sorts the Alias names(red marked)

Could you please make this more visible and understandable as user experience goes lost.

Also maybe add another button for sorting the order of the elements.

This suggestion came from Christoph.
