Hi,
There aren't any tools out of the box for performing batch updates, however, you could write a custom step to fit your needs. To find out more information on custom steps you can look at samples here in your install
InstallLocation\ArcGIS\WMX\Desktop10.2\Developer Kit\Samples\CustomSteps
You can also learn more about our SDK at: InstallLocation\ArcGIS\WMX\Desktop10.2\Developer Kit
Thanks!
Michael
