Nonlinear spherical area load applied to an ellipse surface in PLAXIS 3D

Question

Dear Support Team and PLAXIS users, 
 Could you please help me, whether it is possible to specify a nonlinear spherical area load applied to an ellipse surface in PLAXIS 3D? Something like that: 
 
 The incremental variants do not allow to set a smooth increment in two directions. Thank you in advance.

Hello Rushan, 
 The pizza approach (you can call it like that, I guess) is also a nice idea. Indeed, none of the results is exactly what we want but at least it is something to work with.

Dear Rushan, 
 My approach on this would be to create multiple circular surfaces (intersect them) to create zones at which the load can be considered constant. Each zone can be defined by the increment from the edges to the centre of the circle. Obviously, the more you have, the better distribution, but also smaller elements (e.g. if each surface is of a few cm). 
 Another option is to model the loading by various dummy soil volumes that their only purpose would be to provide a unit weight simulating the distributed load applied. 
 By the way, that is a nice feature we should implement in the future.
