I have a few hundreds to thousands of Simulink models that I need to include in a single Embedded Web View document using the MATLAB Report Generator. To be included, all models need to be loaded in memory. Is there a way to get the same result without having all the models loaded at once?

This is the generation format I am currently using:

models = {'model1', 'model2'}; % Test Simulink models (final version will have 500+ models)
load_system(models); % What I am trying to change
rptgen = TestGeneration('testGen', models); % Create the document
fillslwebview(rptgen); % Display only the models
% Clean up
close(rptgen);
close_system(models);
rptview('testGen'); % View report

With the class TestGeneration:

classdef TestGeneration < slreportgen.webview.EmbeddedWebViewDocument
    %SystemDesignVariables Report on variables used by a Simulink model
    %   Defines a class of report generators to produce HTML reports on
    %   the workspace and data dictionary variables used by a Simulink
    %   model. The generated report includes this information for
    %   each variable:
    %
    %   Value (if the value is a scalar, numeric value)
    %   Data Type
    %   Source (e.g, path of dictionary containing the variable)
    %   Source Type (e.g., data dictionary or base workspace)
    %   Users (path of blocks that use the variable)
           
    methods
        
        function rpt = TestGeneration(reportPath, modelNames)
            
            % Invoke the EmbeddedWebViewDocument constructor, which
            % saves the report path and model names for use by the
            % report's fill methods.
            rpt@slreportgen.webview.EmbeddedWebViewDocument(reportPath,...
                modelNames);
            
            % Turn off duplicate link warnings to avoid warnings for
            % blocks that use multiple design variables.
            rpt.ValidateLinksAndAnchors = false;
            
            rpt.ExportOptions.IncludeMaskedSubsystems = true;
            rpt.ExportOptions.IncludeSimulinkLibraryLinks = true;
            rpt.ExportOptions.IncludeReferencedModels = true;
        end
        
        function fillContent(rpt)
            % Currently empty, displaying models with the fillslwebview function
        end
    end
end
