Is there a way to change the NULL texts of a NULLABLE report parameter to CUSTOM TEXTS like is shown in folloing image .... ?

I have read this question https://stackoverflow.com/questions/17232432/ssrs-2005-how-to-change-the-label-of-the-null-checkbox-of-a-datepicker

And the proposed solution in this forum http://social.msdn.microsoft.com/Forums/sqlserver/en-US/879b0015-b053-40de-b97d-620fc283e542/how-to-change-null-label-of-the-checkbox-in-the-parameter-area
