My Matlab script generates a stochastic Load Profile data and I have a simulink model that is getting this data from 'From Workspace' block. I will call this block LP.
What I want to do is; when I copy this LP block and create another block manually from Simulink, I want MATLAB to detect this change and run the model for a new stochastic data for the new block.
My question is if it is possible to achieve ? Otherwise I have to transfer whole model from Matlab to Simulink.
Thanks in advance.

Right click this "From Workspace" block in your model, select "Properties", select the "Callbacks" panel, select the "CopyFcn" in the left column, on the right panel, type in the MATLAB script or function that generates the stochastic data.

What you need is to use set_param() in the CopyFcn callback to change the variable name in the "From Workspace" block and make sure the new data variable name generated in MATLAB matches it. For example
set_param(gcb,'VariableName','NewData')
