Bulb dim over a certain time?

We don’t always go to bed at the same time, so while sleep routine is nice, it would be even more useful to be able to manually dim the bulbs over a certain time (e.g., 5-10 minutes) when we are ready to sleep.

For example: Create a shortcut to kick off a dimming process over a predefined period of time, Then when you are ready to go to bed, you would simply press the shortcut in the app which could trigger the process

[Mod Edit] Modified description to include the example.
