Combine Matlab-Guide figures / Link a gui to another

Hello Matlab specialists,

I have a (very komplex) GUI, based on Matlab guide. Nowadays I have a simple import function in my "Gui_1", that loads csv files. But in the future I'd like to support even more data types (even binaries)... so I want to replace the import function with a dedicated Converter. This converter should also be another GUI. Something like this:

Here is my question:

Is it possible to link/call the "Converter Gui" from within the "Processing Gui"?

Some additional information:

I would strongly discourage splitting up your GUI in a fig and an m file. That tends to be difficult to adapt. Using only an m file has another advantage: versioning software like git can understand the changes you make.

For general advice and examples for how to create/edit a GUI (and avoid using GUIDE), have look at this thread.

@Rik @Walter Roberson, thank you for your input. I don't see a "like" button so I'll just answer here. It looks more complicated than i'd hope it'll be.

unfortunately it's to late to let go of GUIDE. But I could create another "additional gui" inside of a GUIDE function and use globals to output the parameters?!

%% Example Code within GUIDE to create an "additional GUI"
function push_Converter_Callback(hObject, eventdata, handles)
global output

figure(1)
h = uicontrol('Style', 'pushbutton', 'String', 'Import Data',...
    'Position', [10+100 10 100 25], 'Callback', @push_import);

h = uicontrol('Style', 'pushbutton', 'String', 'Convert',...
    'Position', [125+100 10 100 25], 'Callback', @push_convert;


%-- imaginary "import" function within the "additional GUI"
function push_import(varargin)
global input output

[file, path] = uigetfile('*.csv','MultiSelect', 'on','import CSV-data (multiple)');
input  = load([path,file]);

%-- imaginary "convert" function within the "additional GUI"
function push_convert(varargin)
global input output

output = convert(input)

that should also work, right?
