I go to multiple conferences in a month and am trying to keep track of them in Obsidian. However, some conferences are not one-day. I would really love to see calendar date ranges. For now, I have dots on the days of beginnings, like this

But it is not enough.

Describe the solution you'd like
My query looks like this

```dataview
CALENDAR start
FROM "Conferences/2025"
```

I would like to be able to add additional parameters: finish, metainfo. Finish would create a line or select calendar cells in another way, metainfo would be a tooltip on the bar, or another way to show the meta information. For example name of an event and the location.

Describe alternatives you've considered
I currently have a table like this

But let's be honest: it is really far from the calendar view even if it has all the necessary facts.
