music on hold category syntax

Hi,

In the extensions.conf, I dug up the call screening option. I want to change the torture music to use music in a category i called "torture" i created in freepbx, not "default"
For the line "exten => TORTURE,1,Goto(app-blackhole,musiconhold,1)" How would I get it to play music specifically from the torture category I created?

Thanks
