How can I move a Site Page to a sub-folder?

In our Office 365 SharePoint, (annoyingly) I can only add pages from "New" menu on the site home page.

When I add pages, they end up in the top level of the Pages area. I’d like to be able to move them to sub-folders to structure them, but when I select a page there is only the "Copy to" option (see image).

Does anyone know if there is configuration I’m missing to enable moves or anything I can add in to enable this?

A workaround is to use "Copy To" and then delete pages in the root but I don’t want users to have to do this.

Thanks,

Chris.
