How to set add. Spectre MC options in Assember GUI?

Hi,

In Spectre netlist we can set these parameters for montecarlo: 

23      stdscale=default  Scale the standard deviation by the specified value. The default value is 1.0.
24      process_stdscale=default
                          Scale the standard deviation of process variation parameters by the specified value. The default value is 1.0.
25      mismatch_stdscale=default
                          Scale the standard deviation of mismatch variation parameters by the specified value. The default value is 1.0.
26      nscale=default    N Scale for both of process and mismatch variation parameters in uniform distribution by the specified value. The default value is
                          1.0.
27      process_nscale=default
                          N Scale for process variation parameters in uniform distribution by the specified value. The default value is 1.0.
28      mismatch_nscale=default
                          N Scale for mismatch variation parameters in uniform distribution by the specified value. The default value is 1.0.
29      dist=default      Force all MonteCarlo random variation distributions to the specified type. Possible values are default, unif, gauss and gamma.
30      processdist=none  Set all MonteCarlo process variation distributions to be the specified type. The default type is none. Possible values are none,
                          unif, gauss, gamma, lnorm, sunif and lunif.

But in opposite to many other GUI windows I see no option to set these at least as user-defined option.

Is this correct?

To scale-up only the lognormal+Gaussian distributions I need stdscale=2, and this would be applied to both mismatch & process??
