SplitButton Default Behavior

Is there a way to make the SplitButton dropdown options display when the default is clicked?

Here is the scenario: Rather than using the default (null) value on the SplitButton click, I would like to display the dropdown options (with values) for users to select when the default is clicked. I know they can select the dropdown to the right but what about the main button??

Hope that makes sense..
Thanks

No, this isn't supported. The intent of the SplitButton is to have one primary and some secondary actions associated with a single UI element. You an use a DropDown as a workaround.

Thanks. I appreciate the response.
