After importing the lens from Mesh, we can change the lens parameters only once, similar to position which can be changed easily every-time can we change lens parameters too?

Dear developers,

I need to simulate 3D objects image on the 2D detector through the specific lens system.
Now I can add maximum "three" aspherical coefficient for polynominal terms using the OptiCore.
My requests are following:

1. Any way to add "nine" aspherical coefficient for polynominal terms?
2. How to edit the lens surface parameters after creating the lens? I can't find the "Lens" button.
3. Is it possible to add dispersion (dependence of refractive index on wavelength)?
   Thank you in advance.

It would be really great to be able to modify created lense paramters. At the moment if one clicks some where in the screen, or another menu, after adding a lense the menu called lense disappears and it is neccessary to start over again.....
