hello everyone, I have a checkbox in Bill Payment record called 

To Be Printed

that is when we enter a Bill Payment record. There is another record called Bill Payment(s) which is where we select which of those above Bill Payment need to be selected. In the Bill Payment(s) record, there is a sublist, where I wanted to add the 'To Be printed' checkbox as a filter, however this default NS field does not seem to be available in the sublist Customize option. Does anyone know if there is a way to make that checkbox available as a filter in the Bill Payment(s) records's sublist view?
