Can IE3d calculate a custom formula just like HFSS' "output variables"function?

Hi,every one,can IE3d calculate a custom formula just like HFSS' "output variables"function?
I mean to write a formula in IE3D,the formula is a function of variables,which include s-parameter,port Zo,etc.(obtained from the last simulation),then it can be calculated in ie3d and display in graph form.Can ie3d do this?and how to do it?

I am deeply troubled by this issue.Please help me.
Thanks in advance.
