Helper with multiple selected based on some entity filter or text

Hello,

I have some automations on many cameras. But some time i have to remove some camera from the automation.

There´s a way to create one helper that i can select one or many from a lista ? this list can be based on a entity filter, if so.

and in the automation code i can do this

"if “xxxx” in “helpder.myhelper” then …

Thanks

I think Blueprints solve the problem… if there’s any other way, please post here !

Thanks
