Find names of ports in Subsystem connected to input ports

I have some input ports connected to the port of a subsystem. I know the names of all input ports. How to find the names of ports in subsystem which are connected to inports. For example: If I consider inport A1, I should findout the name B1, which is the name of the port in system connected to A1.

Thanks.

this script will sustitute name of subsystem inport with respect to connected outer inport. It will work also with only some ONE block in the middle between outer inport and subsystem.

% select subsystem
sel_subsystems = find_system(gcs,'Selected','on');
if(length(sel_subsystems)==2)
    sel_subsystem  = sel_subsystems(2);
else
    sel_subsystem = sel_subsystems;
end
block_of_interest = get_param(cell2mat(sel_subsystem),'Handle');
% subsystem inport handle
sub_handles = find_system(block_of_interest, 'LookUnderMasks', 'on', 'FollowLinks', 'on', 'SearchDepth', 1, 'BlockType', 'Inport');

selected_pc = get_param(block_of_interest,'PortConnectivity');
SrcBlock_h = [selected_pc(:).SrcBlock];
%check if connected block is port type block: BlockType == Inport
for blk=1:length(SrcBlock_h)
    connected_blocktype = get_param(SrcBlock_h(blk),'BlockType');
    if (contains(connected_blocktype,'Inport'))
        % Substitute name
        inport_name = get_param(SrcBlock_h(blk),'Name');
        set_param(sub_handles(blk),'Name',inport_name);
    else
        % check block connected to this one
        pc_L2 = get_param(SrcBlock_h(blk),'PortConnectivity');
        SrcBlock_L2_h = [pc_L2(:).SrcBlock];
        if(length(SrcBlock_L2_h)>1)
            disp("Connection Level 2 error. More than 1 connection!")
            return;
        end
        inport_name = get_param(SrcBlock_L2_h(1),'Name');
        set_param(sub_handles(blk),'Name',inport_name);
        
    end
end
