SSRS Filter

Hi All ,

I have created a filter in ssrs named offering .Now am in a complex situation . Its a multi parameter based filter .

I have created a false value for the filter -  'Select None' that will be selected by default from the drop down .

Now the customer don't want to the entire list to be selected but want data for the every offering .

Is this possible . if the 'Select None is default value the SSRS filter will perform filter on each and every offering in the offering column or in short get every value for the offering column in the result .

Please Advice .

Thanks
