Pose flipping with Empties as IK targets

IF I use empties as my IK targets and animate the armature outside of posemode, can I still use the pose-flip feature from pose mode.?
Thanks LB

no, since you cannot select the Empties to flip them, obviously.

Anyway, I find it best to use Bones as IK solvers, since it’s the only solution compatible with the NLA.
