Personas - How do I copy a flavor to another transaction?

Hi,

We are running Personas 3.0 SP7. I need to copy a flavor to different transactions (IW21 flavor to IW22 and IW23). I know that feature was added in SP6 or SP7, but I can't find a way to do it in the flavor or the admin console, and I haven't had any luck searching for documentation on it.

Thanks for your help!
