Client Request is not shown in Template Manager

[sherry.redwalls]

Hi,
I was using Template Manager to send auto notification for the assign user about the client request.
After the latest update, I am unable to find an option for Assignment :: Client Request in Template Manager

I would be thankful for the help,

Best Regards
Sherry
