we should address this issue (which I guess you ran into if you didn't
provide "temporal" Sphere, right?) 

ATM to do it you would need to specify large enough (to get all)
"fake" Sphere for temporal dimension and run searchlight with roi_ids
pointing to first X features which must correspond all to the first
volume within each event (i.e. all having the same event_offsetidx).
