Creating additional anchor points to kangaroo

Hello,

I am currently trying to model hanging fabric using Grasshopper and Kangaroo. Currently I have only been able to create anchor points out of the four edges of the mesh (illustrated in the attached image) however I am trying to create more anchor points within the centre of the mesh at specific coordinate points.

I have tried placing the points in Rhino and then importing them into Grasshopper but when I run Kangaroo it still only acts as though I have the four corner points.

Thank you
