The plugin does offer federation options for each post ; if you don’t want a post to be federated, you can toggle this off as you write your post.

Or did you have something else in mind entirely?

To publish as a different actor, however, I think the best work-around today is probably to create different users, and to change the post author based on where you want your post to be federated. This way your readers can subscribe to @photos@you, or @videos@you, or @name@you, or to your site’s main actor (e.g. @blog@you) which automatically reposts all the posts from all users on the site.
