In the installation directory for Box Of Stops, you will find the application.properties file. This can be used to control a number of installation level settings in Box Of Stops.
Please see the application.properties.default file in the same directory for a list of the available properties you can set. Note this file is just the template, and will be overwritten whenever you upgrade Box Of Stops. The idea is to copy the setting from here, and set it to your preferred value in application.properties.
If in doubt about how to enter a value in this file, please investigate how to edit a Java .properties file, e.g. on Wikipedia.
