Filtering a report

I have a report with a table as the row source. I have command buttons that opens different forms and allows the user to choose criteria, the form then filters the report based on the chosen criteria in the form, but if I use the destination city form to filter the report by destination city, then filter the report using a different form, the destination city filter is lost, is there a way to filter the report with a form by say destination city, then further filter that dataset with another form for say location city.
