Monthly Hue Scene as a Variable

New to the community so hopefully this isn’t something that has already been covered. Looking for a bit of guidance on being able to set a monthly hue scene as a variable that I can reference in my other automations. The hope is that I can have one spot to set all 12 months and their respective scenes and have all my automations reference this so I don’t have to update this information in multiple spots. Looking for a direction that I can proceed with this.

Thanks!
