Selecting control curves through thier joints


Is there a way to do this? I want to pull an Ik chains wrist control and elbow pole vector control by selecting the Ik joint chain. I would then add these to a selection list for a python ikfk matching script

#assign selection
fkWrist = Matchsel[0]
fkShldr = Matchsel[1]
fkuElbow = Matchsel[2]
ikwrist = Matchsel[3]
ikpv = Matchsel[4]
