WINPC NC engrave over curved surface

Hi to all,
I would like to ask is there a way to use WINPC-NC USB for engraving curved surfaces? I have for now version 3.4. I contacted them and they are saying that they still have not implemented it (I wait for this feature from 2017). This is weird for me because I have GRBL machine that I build and on the open source programs I use, it has more options than a software that you pay for it.
So I saw it has the ability to create macros. Is there a way to create my own macros for creating grid and using 3D touch tool from STEPCRAFT to set an offset for the Z axis?
