CST - Adding postprocessing macro using a structure macro

Hey there,

I am writing a macro (structure/global) to automatically build up my planar antenna. Using the parameters I can easily and fast change the geometry by using the history update function.
To further improve the design process I want that macro to add a post-processing macro (under the shift-P window).
Unfortunately the history does not display anything, adding a postprocessing macro. I guess it is not easy, because of the post-processing macros sometimes need further information from the user. But maybe there is a way.

Thanks in advance,
Richard
