I have a set of sub-tasks for a work item that need to be assigned to a manager for on-boarding. I've setup a custom field "Manager" that is a people field. Is it possible to setup a automation that reads the custom field, then assigns the same person to a set of sub-tasks?
Example:
Manager : John Smith
(Rule would assign any sub-tasks that contains "Mgr - " to John Smith)
I've done auto-assign rules for individuals based on a "Flag" (The Mgr -) at the beginning of the summary for the sub-task but I can't seem to figure out if it's possible to assign based off what a field is populated with.
Here is what I've got so far:
I tried using a smart value of the custom field for the "Assign the work item to" and then "user" but that didn't seem to work.
