Dear Guido,
You can certainly do that using the LFP option in DCM (in the spatial
model part where there is IMG/ECD/LFP choice). Prior to that you
should use Prepare to set all the channels you want to model as 'LFP'
and the other channels as 'Other'. Then each 'LFP' channel will be
modelled as a single source in DCM. See for instance the rat
anesthesia example in the SPM manual.
Best,
Vladimir
