Is there a possible way where I link the Sales Schedule Date to the actual calendar of Odoo? 

I'm trying to create a Process Deliveries in Three Steps. (pick + pack + ship)? 

like for example, I created a sales, and I want the schedule date to be sync in the Odoo calendar? 

For example, starting this day, it will be shown the schedule date in the calendar



is this possible to achieve? 


Additional Info, I tried to use Automation but the problem I'm encountering right now is how can I show it to the actual calendar?

So here I create a Trigger On Creation , Status = Waiting, but I don't know what field should I use to show it on the calendar
