I'm missing support to add/upload attachments through scripts.
A use case for this could be to gather attachments from several items in several different workspaces, and collect them all into the attachments of a single item. (related attachments functionality does not currently work for us, as it is limited in what referenced items that are included). This to ease bulk download of attachements, without having to go to several items.
A different use case would be to add/upload files created within Fusion 360 Manage itself as attachments, like excel exports of BOM's, PDF of Print Views, etc.
Also I'm missing support for creating an attachment folder hierachy through scripting. Say you want to always have a default folder structure for your items attachments, and you don't want to create them manually every time... Refer to this similar idea that was archived (we can unfortunately no longer vote on it):
