Hello @jeremy98,

Thank you for providing this, I think I'm with you now. 

If you want to be able to pass a value from one task to another, (similarly to how job parameters can be passed to all tasks), you can define task values. 
https://docs.databricks.com/aws/en/jobs/task-values
Using these you should be able to dynamically calculate the value in one task, then call upon it, inside a subsequent task.

Hopefully, this is more useful than my original answer 😄
