Within a corporate network and with the right permissions it's possible to publish directly to SharePoint from the HTML generation panel.
A SharePoint site/URL resolves to a folder on a server, this means that you can map a drive to it if you own the site in question. Once you have a drive mapped, you can specify the path in the "Output to" field in the HTML generation panel and Bob's your Uncle. For example, I have drive Z: mapped to Sharepoint and I can output to various folders such as Z:\EA Tools\Capability Map etc..
