Warper OpenFX, adding additional stretch points

I just used the Warper openFX plugin today, very cool. However, as I completed my keyframed warper shot. I decided to add a couple more stretch points (the white ones) to finesse the animation a bit further, however adding stretch points will only exist for the previous associated keyframe. Once you reach the next existing keyframe, the new stretch points no longer exist. I suppose this makes sense since this is after all the next keyframe which never had those new stretch points.
I've also tried to add a second Warper OFX on to an additional node; this does not work either. What happens is the frame you are at when applying the Warper FX, the warped image produced from the previous node is frozen. This means you are effectively starting from scratch once again.
SO, I guess the question is what is a solution to adding additional stretch points that can coexist on the already multiple keyframes.
