Is there a way to ignore case in a parameter field?

CRV10 - Is there by any chance a way to ignore case in a parameter for a string field?  I have a {?Last Name} parameter.  The table shows the last names in caps, but the user would not necessarily know that.  I would like the user to be able to enter either brown or BROWN when prompted by the parameter.  My record selection is:  

{EMPLOYEE.LAST_NAME} like {?Last Name}
