I’m not sure that’s doable. The Calendar view in Airtable is just that: it’s a view, and views are tied to individual tables. To have all of the info you want from multiple tables on a single calendar view, you’ll need to get all of that data onto one table. Depending on the structure of your base, this might be possible with a combination of links and lookups between tables, but methinks it would be a very complex setup. Could you describe your base in a bit more detail?
