Automation to Transition lights over time

Forgive me is this has been posted before, but I am looking for an automation to transition my lutron Casetta lights over a certain amount of time ( the current integration does not support this). I saw at one point there was an automation to step up the light over a certain amount of time. So it would look like this.

Call Service turn on lights 1%
Automation to step up lights by 5%, repeat automation until lights at 35%.

Basically do what should call service transition would do but my lights do not support.

Thank you so much for your help,
