Feature request: Change to newer version of shader model

[FilipGaida99]

There is no way (at least described in documentation) to change shader model in hlsl. i can only build for ps_2_0, but i want for example to build for later version to get more arithmetic operations allowed. Is there any way to set/bypass that already?

Maybe we could require writing something like void ps_main_4_0 etc in the shader source to specify the version.
