Vizlib Toolbar Dropdown behaviour

When you have a dropdown in the  Vizlib Toolbar and have no selection it shows the name of the dimension, If you select on value it shows the value and not the dimension. If you select more than one value it shows the number of selections vs total and the dimension name. See picture below.

I have a customer request to be able to choose the behaviour with one selection to show the Dimension name.
