Scheduled Portal Messages

When it’s time to update my client portals (which for me happens once per week) I find that I’m doing this in my phone notes because it’s not yet time to send it. I would been nice to be able SCHEDULE my weekly updates. Then I can write the updates at any time I want. iphone now allows me to do this with text messages. I would be super helpful to be able to do this in the portal. Of course I would also need to be able to edit and reschedule the message if something changes.
