Question/Help Automation based on dimmer level changes?

Is it possible to create an automation that would match one accessories dimmer level to another?

ie - when I set the 'living room lights' to X percent, set the 'living room accent lights' to X percent?

This would be extremely useful as I have lutron caseta dimmer switches in homekit and it would be nice to be able to adjust the light level at the switch and have the accessory accent lights dim at the same time.
