Continuous subject-level covariate of interest

Hi,

I collected skin conductance (SC) data during fMRI, and I would like to use the SC as a regressor of interest (at the individual level) in an analysis that tries to identify edges that correlate with the SC time series (at the group level). To facilitate things, I binned each subject's SC time series into TR-long bins, such that the BOLD and SC signal have the same number of time points. 
Is this something that I can do in CONN? Maybe through the Conditions tab? As in, treat the SC time series as a condition in a task?

Thanks!
