Is there a way to add another button to a mask in Simulink?

I am looking for a way to add another button to a mask dialog. For example, I want a button that will plot a preview of some data that is dependent on settings in the mask. Is there a way to add a button and then customize the callback similar to a GUI in MATLAB?

The ability to add a button to a mask is not available in Simulink.

To work around this issue, a parameter can be added to the mask and a checkbox can be used to display the plot. The example below demonstrates how this can be done.

A dialog parameter of type 'checkbox' controls the creation of a plot. Double-clicking on the block in the model will open the mask dialog. Checking the checkbox will create a plot.

The following code was added to the OpenFcn callback for the block:

set_param(gcb,'showPlot','off');

open_system(gcb,'mask');

This ensures the checkbox is always set to 'off' when the block is opened preventing the plot from being created if it was checked from a previous opening of the mask dialog.

As of R2016b, this feature is still not supported.

Any update for R2022a ? It seems not, but I hope I'm wrong.

Thanks for your answer, but I just realised I did not ask the right question. I want to add a button directly on the Simulink block, just like the "Look under mask" arrow down. Is this possible ?
