Hi Naidu,
yes you can use properties in memberset, f.e. in your ROW, ENTITY memberset you can put AREA="URBAN".
If you want to change dinamically the property you can create a staic combobox with the values inserted and create with excel function the string to use in memberset or you can combine EvPRO with Expansion Functions like evlst or evene to have always the updated list of your area values and put it in combobox, etc.
Kind regards
Roberto
