Gaussian profile in MWS?

I wonder whether is there any way to launch a gaussian profile (the profile of the excitation in spatial coordinates) in MWS? It seems that MWS only have waveguide and plane wave profiles as the spatial profiles. This limits the applicability of MWS in certain cases. For instance, you can not even excite the structure with a waveguide whose plane is not aligned with one of the coordinate axes.

why don't you try another software? like multisim or altium

you can rotate structure to align with Coordinate system
