Allowing a group as a contact

I would like to be able to add groups but have individuals message the group or the group message a individual.

If we set up a group (ops team) and add a few people, currently only the people in the group will be able to see the group and message each other.

I would like to be a me for anyone to see thr group and send thr group a message.

The idea behind it would be that a pilot could send the entire ops team a message with just one contact or vice versa

I am currently using a work around, but it’s time consuming and a bit messy
