How to quickly turn off ALL CUCM 7x/8x trace?

Hi guys,

I just noticed that in CUCM 7x/8x, all trace settings are defaulted as "on". I tried to turn off all of them on a check box or a radio button.... but couldn't find it. Do we have to click through all CUCM servers/service groups/services and turn them off one by one??

Have a nice weekend!
