FluentCRM automation action

it would be great if we could automate booking followups in FluentCRM automations depending on the booking-start and end-date.

We have the ability to start an automation when it is booked, or the booking is completed, but I miss an option to wait until let's say 2 days before or an hour before the start of an appointment or one-off event.

It would also be nice to be able to select more than one event as a trigger
