message to a part of the group

You can send message to the whole group, e.g. to the Worship Team. But how do you send the message to a part of the group that is involved in a particular service? Is it possible? Can you add that feature?

If you are Admin or Editor, you can send messages to specific individuals and groups on the Messages page.

To send a message to, say, 10 specific people and not miss any or send to the wrong person, you probably have to make a list and then select them on Message page, which makes the process cumbersome. What these people have in common is their commitment to worship. So it would be great to be able to filter quickly people out of the group and send messages to selected people. Such an additional filter for a group of people.
