Analogue-sequencer

Is there an easy way of doing the following:
I want to start a certain pattern, say on track 6, at a certain point in
time - based on when another pattern on another track is finishing up. Is
there any way of doing this simply and starting the pattern based on, say an
aux event on another track? The Polymorph can do this sort of thing easily,
internally, as well as from a MIDI trigger, and I'm noping I can do it on
the P3 some other way than, say, copying and pasting blank patterns from
other tracks, or some other indirect method to insert before this pattern...

(I realize that the Polymorph does far less than the P3, which makes it
easier to figure out how to do the more simple stuff...)

not guaranteeing that I won't have more questions tonight...
