Feature Request: Option to add an "extended presence" binary sensor

[Nuuki9]

The ability to trigger actions when extended presence is triggered is great. However aside from controlling devices within MA itself, I'd also like to be able to use that to trigger automations. Unless I'm missing something extended is only provided through the States attribute, but testing for an attribute containing a defined string is tricky to test for - I think you need to use a template condition.

Would it be possible to add an option to create a second binary sensor Area Extended State?
