Overriding series artwork when using OneDrive

I have a question.
There is a note in the support web of Infuse, Overriding series/season artwork is not possible when using Google Drive, OneDrive, or Box.
As overriding movie artwork is possible when using cloud services, why it’s not possible to override series/season artwork? Is there any technical problem? As a OneDrive user, it is really necessary for me to control my library.
