How to use Mask parameters in InitFcn

I am using 2017a. I have a need to use a parameter from the mask of a block in the block property's InitFcn function. Is it possible? I have attached the model so you may see what I mean. Thank you.

You Can access the block parameters of masked subsystem using get_param and change the block parameter using set_param.

You can make these changes inside InitFcn function.

% To get the Block Parameter
Param= get_param([gcs,'/Subsystem'],'Tend');
% To set Block parameter
set_param([gcs,'/Subsystem'],'Tend','6');

I have attached the modified Simulink Model.

a followup question: is it possible to make it more generic so I don't have specify the subsystem name in the following command?

Param= get_param([gcs,'/Subsystem'],'Tend');

This way when the block name changes, I don't have to go in and change this line of code. Thanks.
