Is there an option to add the text in the spModal footer adjacent to the buttons?

I am trying to add the Warning sign in the footer left to the Save button. Is there a possibility using the spModal in AngularJS?

c.addFunction = function() {
        spModal.open({
            widget: 'modal-template',
            noDismiss: true,
            backdrop: 'static',
            keyboard: false,
            buttons: [{
                label: 'Save',
                primary: true
            }],
            size: 'lg'
        }).then{
            alert("Message Saved")
            }
