DMs for all

While it's great for me to be able to communicate with my whole team, specific roles, or teams for individual services, it would be really helpful if team members could DM me and each other.

Use cases:

1) DM from Team Members to Admins:
I sent out a message to my whole team to update their blackout dates and to let me know if they have any special requests as to how often I schedule them. I'd prefer that their replies not be blasted out in a reply-all thread, but they currently don't have the ability to DM me in Planning.

2) DM from Team Members to other Team Members:
When I have a singer or instrumentalist who has a conflict come up, it's part of our team culture for them to reach out to other team members to find a sub and then confirm with me. Currently, they can't do that within Planning since initiating messages is only for admins & editors.
