Is there a way to stop users creating their own taximonies? (locations)


For directory, I have 'Facetious Search' plugin running to allow users to search for dog services by type and location. However, the only locations which have been created so far are ones which have appeared when other people have listed their businesses and then listed hundreds of locations they are able to serve. This is making the locations drop down menu messy, I'd much rather there were simply options such as 'Nottingham', 'Derby', 'Leicester' etc for the people submitting their directory listing to choose from (in a drop down menu when listing). This way, all these sub-counties wouldn't be there. Is there a way for me to do this please?
