Mapping Brep pattern onto a Trimmed Surface

Hi!

I’m generally new to Grasshopper and I am trying to morph a 3D pattern onto 3 trimmed surfaces separately. I’ve tried sporph, box morph, and surface morph and they all map my pattern rather to the untrimmed surfaces. How can I map my pattern only to the trimmed surface (without it looking cut out or too deformed)?
