start simulink via power_analyze using variables from another workspace

When I want to run a simulation within a matlab function I use

clear
clc

myFunc()

function myFunc()
    R = 5;
    options = simset('SrcWorkspace','current');
    sim('modelName.slx', [], options); % This model has a block with parameter R
end

If I don't use

options = simset('SrcWorkspace','current');

MatLab can't find variable R, because it looks for in not in a function workspace, but in workspace of the main script.

Now, I need to calculate not a transient, but steady state solution, thus I use

power_analyze('modelName')

However, It doesn't allow me to pass "option" parameter into it to use 'power_analyze" within a function.

Is there any way to do something with it?
