The easiest way is to edit your configuration file (probably mach\resource\configuration\cam_general.dat) to point to the ude file that combines the default with the Sinumerik.
Change this line:
USER_DEFINED_EVENTS,${UGII_CAM_USER_DEF_EVENT_DIR}ude.cdl,${UGII_CAM_USER_DEF_EVENT_DIR}ude.tcl
To this:
USER_DEFINED_EVENTS,${UGII_CAM_USER_DEF_EVENT_DIR}Siemens_Cycles_plus_ude.cdl,${UGII_CAM_USER_DEF_EVENT_DIR}ude.tcl
