I am not sure if there is a current built in function that will support what you are looking for. I would recommend checking out this post:
If I was attempting to solve this one, I would use the API referenced in this post (or a similar one I can put in our cloud), and setup a random wait time.
HTTP Request - Retrieve random Number
Define Variable - Add the random number to the current time
Wait - Use your variable to define when you should wait until.
It still has a risk of having the ticket creation at the same time if the numbers are too close.
How many loop executions do you anticipate having at the same time?
