Hi there, SI Support!
Good question. Right now, events that span multiple days will indeed appear on each individual day rather than visually spanning those days. We’ve actually seen this idea come into our feature request forum, but it looks like it could use some more votes and it would be great if you added to it. 🙂
In the meantime, I’m afraid spanning multiple days visually is unavailable right out of the box. Sorry about that!
Does this help answer your question? Please let me know.
Cheers!
Geoff
