How to auto add a watcher to an issue from a Custom field

Question

Hi - have created a custom field for a user-picklist for our service desk offering, to allow a reporter to add the "originator" of a call if not themselves. what I need to do now is have the "originator" user auto added in the Issue Workflow as a watcher upon issue creation - so they can then be notified at every stage as well as the reporter.

Cannot see a way of doing this at present. Help!

Jobin - thanks for this. Found the way you suggested - had lost it amongst all the options, and since it is a custom user field, it wasnt in with the normal custom field settings. Thanks!
