Replicate Entities Card Main Switch

[AnderVentura]

Goal

I am redesigning my dashboard. I have one dedicated to lights. In it, I have a card that includes all my lights with a master switch in the header. It’s the native Home Assistant implementation.

I would like to achieve something similar using bubble-card. I’m thinking about a vertical list with a global switch at the top, and then additional bubble-cards below to control the lights in each room. For the tap action, I was planning to open a pop-up for each area to individually control the associated lights.

My question is how to create that master switch in the header. The native Entities card implementation already includes this switch, which is ON if any of the entities in the list are ON.

I would like to avoid having to create a helper or anything similar. Is it possible to replicate this without creating an additional group/helper/script?

I’m attaching a screenshot of what I currently have.
