DocuHub - How to organize inside the TAG

Hi
I bought the DocuHub - A Modern Documentation Theme for Ghost but I am not able to place an order inside a TAG.
Example:
TAG 01 I have POST A and POST B.
I want POST B to be above him. Inside TAG 01 I want to put POST B appearing above POST A

I think you should claim product support directly from the author. You will get better solution there.
