Hi, I have created a deployment flow retrieving currency rates in prefect 2. The flow takes several parameters including a date range to retrieve in the form of

start_date

and

end_date

. The default is set to today's date using the function

datetime.today().strftime("%Y-%m-%d")

. When I create a deployment, the above function executes and sets the date as today's date, e.g.

03-04-2023

. The problem is that this date will be set all the time every time I run the flow tomorrow, next week and next month. Is there any functionality in prefect where I could specify a parameter e.g. prefect.today() which would set the current date each time the flow is executed. Flow params set in deployment
