Vray Proxies transformation

Hi,

I would like to ask if it possible to transform vray proxies files in a cage type transformations (The same way as paneling works on double curved surface) ? 

For now I was playing with grasshopper proxy scatter in a 2D grid. 

Just wondering if it possible to transform proxies irregularly not just  x, y, z axis scale, but taper, shear or similar transformations?

Thank you in advance,

Petras.
