select one element, without fire click-event

[joergenv]

What is the current behavior?

I have made a custom select all-function - implemented as the first select-option on the list. When I select one of the other select-options, I want to deselect the first "select-all" select-option.
I cant find any function in the documentation implements that feature:

What is the expected behavior?

.multiselect("select","value",false)

Seems like you would need to implement some custom logic around the click event.
