select options "TO" field removal

Hi,

I am using select options as F4 help.My problem is that i want user to be able to select multiple options but not as a range.The "TO" field which is displayed along with inputfield i have removed using the add_selection_method of the handler with parameter i_no_intervals = abap_true.But on pressing the F4 help i get a pop up which has fileds as OPTION,FROM,TO.Now i want to remove this "TO" filed as well.Any ideas??
