puredata - Pure Data: storing sub-sequences within sequencer and looping them? -

i'm beginner pd question.

is possible play, say, 8-step sequencer, store sub-sequences of steps , loop them? possible in live context, i.e. hit bang "record" (not through adc though), let sequencer go through, eg, steps 1-4, hit bang again stop "recording," , hit bang loop sub-sequence i've played? (and if is, can direct me guide or throw me bone how go this?) thanks!!
