Dialog: swap/remove icon during runtime

[MudratDetector]

Is there a specific function or method I can use to swap or remove a dialog icon during runtime?  I see where I can revise text with

ACAPI_Interface (APIIo_SetMenuItemTextID, &itemRef, nullptr, itemStr);

but have not found something similar for icon images.

I'm defining the icon by the typical means in the .grc file and loading the default image by typical means in the Fix.grc file.  Graphics on my dialog are permanent this way.

I would like to activate this feature with ::ButtonClicked from my dialog class.  I am monitoring the button click event by typical means:

void JHP_UL_Dialog::ButtonClicked(const DG::ButtonClickEvent& ev)
{
	if (ev.GetSource() == &00Button)
	{
		// press button to make choice/swap out different image in dialog
		// wait for other dialog selections then press 'OK' to do stuff
	}
	if (ev.GetSource() == &01Button)
	{
		// press button to make choice/swap out different image in dialog
		// wait for other dialog selections then press 'OK' to do stuff
	}
}
