It would be cool if there could be a setting on the experience dashboard page where the client can set the go-live date and it would be set in the platform unless they changed the date or removed the checkbox. So any time they came back to reporting the analytics would reflect the go-live date.
I see this being valuable to allow for more accurate reporting when there is test data in there. Eliminates the need for them to always have to adjust the date field.
I can also see this helping our reporting to get a more accurate sense of when clients actually go live.
