I have installed a Plone with the following information:

Plone vr 5.0.7 (5017)
CMF 2.2.10
Zope 2.13.26
Python 2.7.13 (default, Jul 26 2017, 16:31:12) [GCC 4.3.0] PIL 1.1.7

Was wondering how can I relate a field (when you add a field on content type) to an action!
So the idea is to create a field that admin can choose which user group can receive an email/notification when the content is published. I know I can add a rule content for emailing but I would have a choice to choose which user group can receive it. Could be an add-on or something in Plone?

Thank you!
