Is there a way to remap the parametric coords of a curve?

I have a starting “trunk curve,” which I am copying 3 more “branch” curves to. I merge all 4 together and then use a vopsop to push all 4 points P along the parametric coords of each curve ($PT matched to $PR) using the prim attrib vop.

My problem is that as I move the slider controlling U to move each point, all the points move at once. What I want is for each of the “branch” points to only start moving as the “trunk” point reaches them.

So basically, the first “branch” point would have a parametric range of something like 0.3-1 and only start moving once the slider got to 0.3. The second “branch” point would have a range of 0.45-1. etc.

Originally I was thinking that I just needed to remap the uv point attribute (which I've done), but the point uv seems to have nothing to do with the uv parametric coords of each prim. So I'm a little stuck on this at the moment.

Here's a hip file of my problem, thanks for any advice.

Hi there. I think you can try Basis SOP for this.
