How to modify number of "Days" option for CLASS

I would really like to know if there is an way to modify the number of days option for a class in BF. Currently there is a drop-down with options I need to change that to 60 days but the max number that is available for selection is 45. I need to keep the logs for 60 days and then purge them.

Request your help here.

Thanks.

use BuildForge::Services;



my $host = 'localhost';

my $user = 'root';

my $password = 'root';

my $buildClassName = 'Scratch';



my $conn = new BuildForge::Services::Connection($host);

my $token = $conn->authUser($user, $password);



my $buildClass = BuildForge::Services::DBO::BuildClass->findByName($conn, $buildClassName);

die('Could not find build class ' . $buildClassName) unless defined($buildClass);



$buildClass->setPurgeDays(60);

$buildClass = $buildClass->update();



$conn->logout();

$conn->close();
