UWL email notification service filter

Hi all

We've activated the email notification service and it's working as supposed, everyone is receiving its tasks on the web (not portal) mailbox.

Now, we're trying to configure an email-filter in the UWL iview, just for the CRM tasks. We need that, once they get to the portal mailbox, they're only sent to "some" of the assigned users, so just a group of them get the email, instead of spamming everyone.

Is there any standard way to do this?
