Feature request: Automatically modify issue label after user-supplied date

What about automatically changing a label after a certain date?

Use case:

Let’s say there’s a marketing campaign X scheduled for 3 months from now.

Issue: Can’t send marketing emails on campaign X

Feature:

  • [ ] Update label _[low priority]_ to _[high priority]_ on _____

Right now, we’d have to do this programmatically and have a reliable service that would update the issue labels.  Or manually remember to change them as the time comes.

You may want to take a look at the Reminders Probot App. It doesn’t do exactly what you’re describing, but pretty close.
