How do I double book myself?
If you ask your assistant (in your favourite chat platform) to schedule a meeting at a specific time, but you already have a meeting at that time you will be presented with the option to "Book Anyhow". If you choose yes then your assistant will ignore the conflict and double book you.
This option is only available for meeting requests made for a specific time (e.g. "meet with Alexey on Tuesday at 4pm"), and not for open requests (e.g. "meet with Alexey next Tuesday").
