Can I make a report in PI 3 to show when APs were first registered?

I've been asked to come up with a history of sorts to show AP density growth over time.

I can probably manually create this from the depths of my email but I figured Prime should know when APs first come online - the question is does it save that and can I get it out with a report somehow?

I tried a few likely suspects in the Reporting Launchpad: AP Summary, Inventory, Wireless Uptime - but none of those are what I need.

Is this even possible or should I give up now?
