Newbie Question EEG Marking

Hello, I am relatively inexperienced as far as programming goes. I was not part of the team that set up the current iteration of BCI2000 that we are running but I would like to add an event marker to the EEG that can be used in EEGLAB to better evaluate the EEG. We use the StimulusPresentation module to present "left hand", "right hand", and "rest" to the individual. Right now only have StimulusBegin markers and I have been trying to add different event markers for the different stimulus. I have been unsuccessful so far, I am sure it's not complicated but I'm not quite sure what to do. Thank you.

The value of the "StimulusCode" state (marker) contains the information about which stimulus was presented. The number refers to the column in the Stimuli parameter.
