You bet, you can do that via Flowsana - that actually is the exact use case Richard was talking about!
Just build a rule: "When the field ‘Job Status’ changes to ‘ready for review’ (or to whatever value), then Assign the task to the value in the custom field ‘strategist’.
Just make sure that all of the values in the strategist dropdown list match exactly either the username or the user email address of some user in your workspace.
