I like Jim's suggestion, but here's another that might work. Change the title of the Local Data Filter. You can click on the title twice to enter edit mode, then type another title.

Using JSL, it would be:
Names Default To Here( 1 );
Open( "$SAMPLE_DATA/Big Class.jmp" );
Oneway(
Y( :height ),
X( :sex ),
Means( 1 ),
Mean Diamonds( 1 ),
Local Data Filter(
Title( "Choose age(s) to display" ),
Add Filter( columns( :age ), Display( :age, N Items( 6 ) ) )
)
);
