At present, the text typesetting is used to input the Enter key. In three Asian countries (China, Japan, Korea), design often vertical typesetting to be typeset, request to add this function, I hope the official can see, thank you.

The desktop versions can't do this yet either and people have been begging for it for a long time.  Evidently Serif considers this something that will take significant time to implement and they are focused on other features for now.
