TextMesh Pro TMP_InputField OnSubmit hidden in custom editor

Is there any particular reason why the 'onSubmit' event is not included in the TMP_InputFieldEditor? If it's for clutter reasons, surely you can just stick all the events into a Foldout like the other settings?

I would have thought having easy access to the onSubmit event would be generally desirable for an Input field.

Haven't done it yet, but it does look like I can easily add an event listener through the exposed property in code, so shouldn't be an issue, just a mild inconvenience / detracts from an in-editor work-flow.

PS. also seems like 'Line Type' = 'Multi Line Submit' still adds a carriage return to the input field after the submit event? Maybe happens somewhere like late update, because I had to yield to next frame to clear the text.

Code (CSharp):

1. private IEnumerator ClearInput()
2.     {
3.         yield return new WaitForEndOfFrame();
4.         chatInput.text = null;
5.     }
