Choose an empty Value on a Button

Hello, I have a Field called "Regalmeter" and I want to choose every Value instead of the green one in the Picture with a Button. Is there any way to do that?

Use 'Select multiple values in a field' action and use expression like:

=Concat(distinct {<Regalmeter={"=Len(Trim(Regalmeter))>0"}>} Regalmeter, ';')
