Max results Dropdown filter?

Hi,
I was wondering if there is a similar filter to wpsl_dropdown_category_args that allows us to edit the Max Results dropdown? I’d like to set the default value text to “Results” as I have hidden the labels due to some layout constraints.

At the moment I have used CSS but its not very elegant and doesn’t work well in ios…

#wpsl-results .wpsl-selected-item:before {
    content: "Results ";
}
