Function Call UI Command

Is there a way to create a function call for ToggleShowTransformBox
I am trying to be able to call this in a EUW on a current sequence.

I do not want to shortcut key inputs. I do want to be able to call using a button

	UI_COMMAND( ToggleShowTransformBox, "Transform Selection...", "Transform the selected keys and sections by a given amount", EUserInterfaceActionType::Button, FInputChord(EModifierKey::Control, EKeys::M));
