Trim unique surface with plane

Grasshopper
1

Hi all, been trying everything but nothing works to trim this surface by that plane. In Rhino can do with split isocurve and shrink “yes” but need the geometry to remain in GH for the larger scheme of things. Is this not possible inside GH? Thanks.

I split the curves then used some pufferfish components to put them back together, its a solution, there are probably better ways to do it
