I want to be able to see net new users added to Iterable for a given time period, and I'm okay with saying "give me everyone with a Signup Date in the past 7 days", but I don't see any way to add that to a Dashboard or a report.

I thought that, failing a net new report, I could look at list or subscription growth, but no, those aren't available, either.

How are others tracking overall user growth?
