All APs MACs can be exported (as you state) as image below...does this help?
edit: zones/groups don't show but a little bit of XL rearrangement might put them in the groupings you want. If you originally put your APs in some logical order (by IP or name) then sorting will be easier. Obviously you have to know your APs and groups or refer back to ZD gui repeatedly...but it can be done if clumsily!
Correct Bill, just the management MAC. The BSSIDs are only available through the individual AP info pages in Zone Director. There is some logical assignment to them (by band and name) but unable to figure it out enough to be confident of predicting.
