How to know which inport-block belong to which From-Block ?

Hi everyone,

This is an exemple of my question. Imagine that i have a lot of subsystems and in the main-system or in the subsystem itself there are too many of From-Blocks.

my question is: how to detect the the selected signale in the subsytem belong to which From-Block. In another way which inport-Block belong to which From-Block

This will work only if the Inport-Block connected in sorted way with From-Block

for exemple: [A]-Block will be detected as From, [B]-Block will be detected as From1 and Inport-Block will be detected as " 1 " , if i run my code it will work fun.

but in case that [A]-Block will be detected with From10 or another number. so how can i know programmatically that selected signal belong to which From-Block

Hier is my try:

% Select Signal data from the Simulink Model
selectObj     = find_system(gcs,'findall','on','selected','on','parent',gcs); % get the selected object
parent_handle   = get_param(selectObj,'SrcBlockHandle');                      % get parent  handle (in this case Inport-Block)
block_type      = get_param(parent_handle,'BlockType');                       % get the block Type
parent_path         = get_param(parent_handle,'Parent');                      % get the path of the parent (in this case subsystem)  
parent_path=strsplit(parent_path,'/')
parent_path(end)=[];
parent_path = strjoin(parent_path,'/')                                        % get the path of parent parent system (in this case main system)
Blocks_From     = find_system(parent_path,'SearchDepth',1,'BlockType','From') % find all existed From-Blocks
port_nr         = str2num(get_param(parent_handle,'Port'))                    % get the number of Inport-Block
signal_name     = get_param(Blocks_From{port_nr,1},'GotoTag')                 % get the name of the from-Block   

I hope someone can help

thank you in advance
