I just got up to redeemable level (60k miles) and coincidentally I have received recent AA emails about mileage redemption promotion, "as low as 5,000 one way", ending tomorrow.

Neither on that promotion page, nor on aa.com generally, can I find what I really want: an awards calendar based on mileage. From STL. To find out where can I go for those 5,000 one way fares (or 10k or 15k), and on what days? Instead, it makes you start in reverse (put in the destination & date), then it tells you mileage required.

Even without the promotion, I would want it the other way around -- give me some destination/date choices arranged low to high in mileage cost, then I will choose. I don't know the destination or date independent of knowing the mileage required.

Any way to attack a search in the way I want?
