Set retention for Applications and Services logs in Windows 2008/2012 using the registry

I need to set the retention for one of the logs in the Applications and Services Logs section of Event Viewer for ALL my servers.  This means I need to do it via a preferences registry setting in group policy.

When I made the retention setting for the Windows logs, I was able to add a Value named Retention in the key for the log, for example:  HKLM\System\CurrentControlSet\Services\EventLog\Application --> Retention = 0 (REG_DWORD).  (Yes, I know I could have done this through Administrative Tools, I chose to do it through the registry.)

I know the location of the Applications and Services Logs in the registry:  HKLM\Software\Microsoft\Windows\CurrentVersion\WINEVT\Channels --> <name of the log>.  What I am trying to find out is the name of the value to add.  Will "Retention" work here, as it does for the Windows logs?  Or is there a different Value for these logs?  Any help will be much appreciated.
