When dealing with variables that prompt for input when a configuration is run it would be nice if you could specify whether it always used the last selected value or used the same default value each time it runs (which might be different to the default specified when the build is run by a schedule). This would allow a default value for something like "don't do this really time consuming task" to be false every time, with the user then having to explicitly select "true" (i.e. do some long and horrendous task)
